I'm in the process of switching out all the possible bulbs to LEDs.

Interior dome incandescent:


Interior dome 6x LED:


Rear high mount stop (3 of the 5 incandescent bulbs were burnt out at the time) and license plate (both incandescent bulbs were burnt out):

Also, the plug and socket for the upper bulb were melted. I had to get a replacement assembly. The same thing was happening to the right side, however, I changed it out for the LED right in time.

Rear taillights and flashers (I'm aware that I need an electronic flasher for normal speed flashing, probably get that tomorrow. And did not get a shot of the back up lights):


Rear taillights with brake pedal down:


Front flashers (I left these with incandescent bulbs because the left flasher is wired with negative polarity. Go figure. But I got a shot anyway):



All that's left is brighter high mount stop (4 LEDs per bulb vs 1 LED per) and the trunk light. Bummed about the front flashers, though.

I had to buy a 36mm Festoon bulb because the 31mm Festoon that I bought was too small!



I have a replacement bulb coming in for one of the front flashers and will try it again.
