Here is the headlight switch mod.
1 3.2mm x 1.8mm LED from Mouser.com http://www.mouser.com/ProductDetail/...KevPv2k5b2IKR3
1 2.2mm x 1.4mm LED from DigiKey.com http://www.digikey.com/scripts/DKSea...73383494640765
Remove the vent with the headlight switch in it, then unplug the switch and pop it out of the vent. It just pushes out from the back.
Once you get it out, back at your workplace, remove these screws.
At that point you will see the board, all greased up. Leave it greasy, but be careful not to get it everywhere. Especially where the LEDs are. Take note of the retainer tab.
This is what we're working with. There are 2 different size LEDs in the headlight switch. The main one is just like we used before on the door switches. The smaller one is a 2.2mm x 1.4mm LED.
Same as before, just reverse everything to put it all back together.
Here's a pic of the finished product.
