in the process of making custom LED ring 6th gen headlights. not willing to spend $150+ for aftermarket ones. i know this is a shot in the dark, but does anyone know the circumference of the opening inside the headlight around the bulb housing? i dont have a spare set of headlights to open up and check.

 

Not sure, but you could do it the math way. Measure the diameter and then multiply it by pi.

 

im trying to find the info without having to separate my head lights multiple times lol. its my DD so trying to do this once and only once

 

Just measure across the lens to get the diameter of the circle and then divide that by pi. It won't be exact but it should give you a pretty good idea.

 

yeah i guess i can do that. was looking more for the diameter closes to the inside of housing where the hole for bulb insert is but ill wing it

 

When I get home I will try to measure the one I have sitting in my closet.

 

that would be extremely helpful thank you

 

Diameter of each is 1 1/4 inch (1.25) so circumference is 3.925 inches

 

is that for the DRL and low beam openings?

 

That is for both clear lights and the yellow turn signal bulb openings. All three openings are the same size but they look like they aren't
