Are they supposed to light up as a brake light?

 

yes - 10 characters

 

10 characters? so those inner tail light bulbs use double filament bulbs?

thanks,

supraboy- i had to meet the minimum number of characters to post which is 10 characters.

I believe the inner tails need double filament bulbs. I've never had to change them nor have I ever looked, I just swapped out my whole set for LED tails and I noticed the inners also get brighter if I hit the brakes.
