Gah this is so annoying. All I want is my tail lights to be led for when I leave the park lights on. But because they are combined brake/tail bulbs its just one thing after another...
The latest is that once I established that I got a faulty pair the first time, I decided to buy some decent BAY15Ds.
I also hooked up the unused bottom rear fog light incandescent bulbs to come on with the brake lights. This means the ECU will still see the correct current when the top brake lights change to led. It should also be safer since its two more unique brake lights that come on, rather than just the combined tail/brake light.
But.
Now the fancy new bay15d led bulbs I bought don't work either. The problem seems to be that when in park/tail light mode, the brake light circuit also has around 1V on it, and somehow this is causing the led bulb to freak out. The led won't light, and it gets hot with an odd burning smell. If I insulate the pad for the brake circuit on then led bulb, it comes on in tail light mode just fine, but obviously no brake light mode working.
I just want it to work, but it is conspiring against me.
