TO ALL PERFECTIONISTS: This light bulb thing has been KILLING ☠ me for the last few days. I tried several different bulbs (Sirius, Teguangmei, Everbright) and remained totally unsatisfied. The deep rich yellow of the front turn signals was completely washed out by utter blinding and Easter

yellow light. I ended up doing a bit of research on SMD lights, lighting strips, adapters, everything. I came up with a
solution and some information. (SKIP TO SOLUTION to avoid my ramblings)
INFORMATION
1. Most bulbs use 3030 or 2835 SMDs. These are the BRIGHTEST

and highest wattage bulbs typically used. They're popular in hyperflash applications because if enough are put together, they can result in a significant wattage to trick the relay system. Unfortunately they are CRAZY

bright. The SMDs inherent properties
DO NOT VARY from bulb to bulb maker when using the same SMD #. AKA Lasfit SMD 3030 is the same as SiriusLed 3030. The difference is bulb design (safety features, etc).
2. Attempting to place a relay on your lights is TOUGH due to the wiring scheme, with the ground wire running to multiple lights. Mounting a resistor within the housing is possible but SKETCHY as its a plastic mount. Mounting it between the light and car is impossible. Only mounting it inside, on a screw post is likely possible. It's alot of effort and opening the light housing wouldn't be fun; it appears to be plastic welded. No thanks

.
SOLUTION (until somebody makes some
aftermarket LED bling). Please perform at your own risk ⚠.
After playing with multiple bulbs, different colored sharpies, learning how glass paint works, having several glasses of wine

, and staring at my car for hours

, I discovered a way to reproduce the
perfect yellow 
to match the front lights and at a
brightness that is also perfect.
For Reference these are the bulbs that I used. LASFIT would also work great.
Teguangmei Turn Signal Bulbs. These use SMD3030s (same as LASFIT).
Using a
Black Sharpie (industrial strength for good measure), I blacked out 5/9 of the SMD chips (On Lastfit, I recommend only 2, as only 6 SMDs exist per side). This SIGNIFICANTLY improved the brightness issue. However the color washout remained.
Using a
Yellow Sharpie I filled in the remaining SMDs and then reinstalled (same for LASTFIT). This resulted in a LITERAL PERFECT COLOR MATCH to the front bulbs with brightness matching the front turn signals.
See this example picture of how this works.

IF YOU MESS UP, don't fret
. Use a dab of 90% isopropyl etoh on a cloth and wipe the sharpie clean and wait to dry.
I didn't take a video of the lights on because cameras seem to have significant trouble capturing the differences in color. Just trust me on this color thing. Just... do it. Trust my

.
Hopefully this solution will remain permanent. Sharpie is fairly heat resistant (industrial to 500F).
