If anyone knows or has a min up check the length of the center bulb in the factory 01 dome light would be great I'm not next to my truck and can't seem to find the info on the web. The middle bulb is a festoon light and super bright led needs the length of the bulb to match it

 

I think it's in the 38mm to 41mm range but it's been a while since I changed one in that style dome light.

 

212-2....aka 44mm.

This is the "bubble" dome light with the two 168 outside map light bulbs and the center festoon bulb. Stock in my '01.

 

Perfect thanks !! you saved me ! I don't have my truck by me so i couldn't measure it

 

Well, at least I was in the ballpark HA!

 

It's all good !! I gotten coming from super bright led along with back up lights and corner lights .. I haven't decided on what ones I want for the parking lights yet
