Bought these for a 2003 Avalanche (with body) and they work great during the day when my headlights and taillights are off. But I have *AFTERMARKET* rear lights with integrated LEDs and they are very annoying. My turn signals don't work at night. My turn signals don't blink. The light does not turn orange. Nothing. I lose all turn signal functions at night. But during the day they work perfectly. I took them out, put in regular bulbs and got my turn signals back! I've read that aftermarket taillights and turn signals don't go well together, so do your due diligence. I had other switchable LEDs in that truck with those fancy taillights. But they were cheaply assembled, and the housing of one of them broke and dangled loosely in my headlight housing. That's why I bought these. The bodywork is much sturdier than my previous pair but I need the turn signals to work lol. Also yes, they hyperflare. But who cares. My taillights hyperflared when I bought them 2 years ago. Aside: I've tried turning my fancy taillights off and back on to see if anything has changed, and the results are conclusive. They worked for several minutes. Then I lost the turn signal function again. So it's easy. funny laugh.
