Genesis Sedan bulb sizes

[bbk]

To Gimli: Thanks for the bulb size info. Just checked my 4.6 w/Tech; the front footwells have the same bulbs as the puddle lights in the door: 168 (194), one each for driver and passenger sides. (It's interesting that the footwell bulbs have a blueish, rubbery sheathing slipped over the glass portion of the bulbs, whereas the puddle light bulbs do not.) You may want to add the vanity mirror lights to your list as well. Driver and passenger sides require one each of the 31mm festoon bulbs.

Alright, here's another bad news. The rear blinker bulbs are NOT standard 1156 bulbs. The little side posts on the base of the bulb used to keep it in housing (push-and-twist) are not at a 180 degree angle from each other, like standard 1156 bulbs. They're at approx. 170 degree instead so when you slip the bulb into the socket the one post keeps it from being turned so it won't lock in place. I also think they might have reversed the polarity of the socket because even with the bulb completely pushed-in it won't light up.

I haven't had time to really look into it and figure it all out (weather is quite messy out here today) but hold off on buying LED blinkers for the rear unless you're willing to take the risk of the bulbs not working properly.

I haven't tried the front bulbs yet, I hope they don't also have some weird base.

the front and rear turn signal bulbs are different than one another.

I check and can't remember which is which, but if I remember correctly the rear bulbs are the 1157 (dual circuit) and the fronts are 1156 (single circuit)

Re: Genesis bulb sizes

You can! All you have to do is turn on the parking lights and than makes sure the fog light switch is turned on.

I stand corrected.

Thanks guys

I know. See the first post in this thread.

It's the opposite. The update is that the rear bulb is NOT a standard 1156 bulb. It is NOT an 1157 either, it only has one contact.

Thanks for the info! Unfortunately we're not allowed to edit our posts after 24 hours but I'm trying to get that figured out with the people in charge

Either way the info is in the thread now so hopefully people read through all of it

Gimli, if I may chime in on the turn signal lamps - From what I've seen, I'm going to guess that the 1156 lamp is a type P21W bulb, with a BA15s (bayonet, single contact) base. The rear turn signal lamp I just pulled out of its housing is the European PY21W amber bulb (made in France by Philips), which has a BAU15s (bayonet, single contact, skewered pin) base, more common in European autos. You're absolutely correct; 1156 lamps will not fit our rear turn signal application. (I've not laid an eyeball on the front bulbs; my hands and arms are over five years old!) Luckily, if one needs or desires to change the bulb, there are plenty of colored glass, stealth glass and LED bulbs out there available with this curious BAU15s base. I guess simply changing the electrical fitting to one that accommodates the more common 1156 lamp would also work, which would open things up to a much wider variety of lamp manufacturers, styles, colors, etc.

 

[Gimli]

Yep, that PY21w bulb looks just like the one I pulled out of the rear blinker. 7507 seems to be the North-American code for that type of bulb, which may make the front ones 7225, the dual-contact equivalent (unconfirmed).

Unfortunately I haven't found any retailer that sells good LED replacements for those formats.

 

[bbk]

It looks as though our friends over at Autolimination have a few. This one is their 7507 PY21W Tower European Bulb.

I'm hesitant to order these since I'm unsure whether these LEDs (and others like them) would be prone to line load issues when using them to replace incandescent bulbs. I do want to replace the OEM bulbs though; the "fried egg" look just doesn't seem fitting for the Genesis.

 

[bbk]

I finally pulled the front turn signal bulbs out. They are 2357, 12V, dual filament (28/8W) bulbs with the BA15d (bayonet, dual contact) base. So, they decided to use different bulbs, with different bases, for the front and rear turn lamps. Really don't understand. A dual filament bulb in an application where the 8W filament is never used! Worse yet, I've been unable to locate an LED bulb with the BA15d base and amber color. Oh well.

 

[Gimli]

Are you sure it's a BA15d base and not a BAY15d base? "Normal" 1157 and 2357 both use the same BAY15d base.

Are the two pins level with each other or is one higher than the other? Here are diagrams of both socket specs:

Gimli, thanks much for questioning and making me double check. I stand corrected; the base for the front turn signal bulb is indeed the BAY15d.

Re: Genesis Sedan bulb sizes(center console)

Does anyone have the bulb size for the center console(between seats). Can you just pop the lens out to change it or do you have to take the console apart.

Alright, here are the results of my most recent adventure...

I've replaced the high beam bulbs for Silvania Silverstar Ultra H7. Found them at my local Canadian Tire, $60 for the pair (ouch). I replaced only one and tried to see if there was a difference between those and the stock H7. I can see that they're brighter but the colour seems pretty similar to the stock bulb. I'll have to try them at night to see if it's worth the $60 but so far I'd say probably not.

I've also changed the position bulbs that are next to the high beam bulb with a set of those. They look very good, bright enough to see and very white. I'll have to wait and have a look at them at night to see if they provide as wide a beam as the bulbs bbk used here but I'm sure they'll work just fine since they're just position bulbs. At $10 for the pair, they're also not too expensive.

Now I tried the 1157 LED bulbs I got a while ago for the front blinkers and they work very well. They are bright (maybe a bit brighter than stock but not much) but not blinding and have a very nice, deep, amber colour. Unfortunately they do trigger the "burnt bulb" high-flashing cycle so I didn't keep them in. We'll have to see if there is a blinker relay that can be changed to fix that or if we're stuck with using load resistors to simulate a normal bulb, which I will not do. I used load resistors on my previous car and they're a pain in the bottom to get right and can represent a fire hazard. They do get extremely hot.

Note that I didn't have to remove the headlight assembly or the bumper skin to get to any of those bulbs. All I had to do was remove the three bolts around the driver-side fuse box and move the box out of the way to get access to the left-side bulbs ans remove the airbox to get access to the right-side bulbs. I also removed the two nuts holding down the power steering fluid container and moved it out of the way to access the right side blinker bulb.

I have found the 31mm festoon bulbs to be 3175 not 6418. The 6418's are larger, and yes they can be made to fit. The 6418's may be a good way to go if ultimate briteness is what your after. But, standard size with no bending of wires, is 3175.

I would like to slightly dim the license plate bulbs as i have a white car and they glare off the paint surround a lot and thoughts? Also what is a 37mm festoon bulb anyway and where would I buy such a thing Guess I am out of it never ran across festoon before

Thanks Grip

I originaly replaced them with Pilot LED bulbs from Pepboys. They were a nicer color and dimmer than the stock bulbs. But I would consider them too dark to use anywere else.

Also what is a 37mm festoon bulb anyway and where would I buy such a thing

They look loke double ended bullits. Contacts at each end with glass in the middle. Any large auto parts store should carry stock types of these, with "better" LEDs redily available in the after market.

 

[GripperDon]

Thanks, Will get them this week end. Familiar with the shape but somehow missed the name (senior moment )

I must admit I tried the V-LEDS.com bulbs that Gimli tried,

("Now I tried the 1157 LED bulbs I got a while ago for the front blinkers and they work very well. They are bright (maybe a bit brighter than stock but not much) but not blinding and have a very nice, deep, amber colour.")

and found they were no where near as bright as stock. Maybe at night on a lampless street, but certainly not in daylight. They are barely noticeable.

I have also tried 60-LED towers for the rear turn signals (at $40 each), even another 'high-power' variant, and still quite pitiful compared to stock. IMHO, it's going to be a while before LEDs are as bright as incandescents regardless of price. AM disappointed, but I'll take safety over 'cool' any day....

Can anyone provide help with front parking light bulb replacement? I have replaced the highbeams, but I would like to replace the parking lights with something whiter (I have HID's on low). I don't want to force the sockets, do they twist, snap? Anyone replaced these and found good LED's? If not I was thinking of PIAA's, they make a "blue" bulb that is supposed to be white.
