It doesn't interfere with the main beam (not noticeably anyhow), it sits around the outer edge of the reflector.
It's difficult to get a decent shot in the dark...
As I said, not as bright as I'd like.
The LEDs (one in each end of the ring) are 12000mcd, you can get them up to 28000mcd but I thought the ones I got would be enough, plus they were pre-wired with resistors for 12V DC.
I'll be ordering some more much brighter ones.
I also didn't use hexagonal Acrylic rod, I used round as it's all I could find at the time, and instead of cutting slots I ended up using a coarse sanding disc to give a rough surface to refract the light, it gives a more even glow but I think it needs the slots to achieve maximum brightness (along with the brighter LEDs).
It took longer to get the ring to the right size than it should, you have to find something the right diameter to form it round when you take it out of the oven, and I tried a few different things beforew I found the ideal one.
The rings spread slightly as they cool as well, so you have to hold them to the size while you cool them under cold water.
I'll make a jig for the next ones.
The trickiest part was wiring them in, feeding the wires through the bulkhead wiring 'boots', and through the two rubber bungs the bonnet release cable goes through.
I took a feed from here...
I wanted them on whenever the ignition was on, this was the first wire I found that suited.
