Step 1

Taillight

⌕

This is the best guide to disassembling your BMW E21's taillights to replace a bulb.

Step 2

Repair step

⌕

Remove the two plastic nuts holding the taillight lens in the housing.
I recommend putting a towel in the trunk/boot so the plastic nuts do not get lost under the carpet.

Step 3

Repair step

⌕

Pull the taillight lens out of the housing.
Be sure to use both hands to remove the lens instead of one hand, especially if your taillight lens is cracked. (If you try to remove the lens while using one hand, the lens may get stuck on the screw stud and snap off.

Step 4

Repair step

⌕

Remove the light bulb by pushing into the housing on the bulb gently, and then unscrewing it and pulling it out.
Do not grip the bulb too hard, it may break!

Step 5

After the replacement

⌕

The bulb now functions as intended. Good job!!
