now that your interior lights work.

you can upgrade the bulbs to led's

best way to make sure you order the right size is to take a caliper and measure the bulb you want to replace.

this pictue is of the dome lights in the headliner of an e30

1.680 inches

convert this measurement to millimeters

 

42.6mm for the dome lights.

most sellers online sell 42mm, which is what i bought and it worked fine.

37mm for trunk lights

37mm for glove box lights

working dome lights

 

if you get a flat panel led you have to solder it to the light housing to orientate how you want the light aimed, or else it will just rotate in the housing.

before and after

before reinstalling the housing check if you placed the led in the correct orientation

led's have anodes and cathodes

anode being the positive side

meaning the led will only work in one orientation.
