Stop light upgrade to avoid getting rear ended.

It hurt my eyes. Photos don't do it justice.

I think even a millimeter or two would make the difference in fit. It can't be much more than that or the LED would contact the lense. I have an NOS tail light housing somewhere -- I'll try the bulb in that and get some more accurate measurements.

Here are some detailed shots showing the LED fit in a Type 34 tail light housing. First, a factory spec 6v 5W bulb in place. Lots of room there. The reflector is concave to project light outward.

Here's the CuLayer LED in the socket. The diameter is OK but the heat sink bottoms out on the concave reflector.

This shot shows the limited space for the bulb. The inside part of the lense projects about 7mm into the center ring, which gets pretty close to the LED.

Here's the back side of the housing. The pegs on the bulb base aren't able to engage fully with the socket.

I think if the base was about 2-3mm deeper it would be able to seat properly and the LED would still clear the lense.

I saw your picture and it looks a bit brighter than legal for a running light. for brakes it looks very good! 6v right?
