Like so many others I've had many of the turn/DRL bulbs burn out. This week, however, I discovered an interesting fact about these turn signals. My Genesis is a 2015 3.8.
I decided to measure the temperature of the bulb socket's back - with it still in place in the turn signal housing (driver's side, easier to get to, as many of you know). The thermal
scanner showed a temperature of just short of 200 degrees F. This was after I had made a short 20-minute drive with the DRL lights on.
Clearly this is way too hot, so I've decided, like so many others, to leave the DRL off.
I should note that the day before I removed the bulb (2357LL) and carefully cleaned both socket contact points.
Might have to consider LEDs...
