ADVmonster H4 R3 LED Headlight

[Randy B]

Cool! Glad to see it worked out. I'm still thrilled with mine, the R2 version, but this R3 is a completely different design. From the looks of it, I'm guessing you didn't have to modify the retention spring like I had to, which is a huge benefit. That little modification wasn't the easiest thing to do, and although I wasn't too worried about messing up at the time...I should've been; replacements are hard to come by. The flexible heat-sink definitely has it's advantages over the bulky segmented design of the R2.

Were you able to use the rubber dust cap? I couldn't, but it doesn't seem to be necessary anyway...these things are apparently 100% dust and water proof. No problems so far.

I also noticed the R3's high-beam LED is on the bottom, whereas both of mine are on top. It'll interesting to see how that works in the weeks to come.
Anyway, I hope you have great luck with it...keep us posted.

I'm confused. I don't see an R4 version on the ADVmonster website, and their literature seems to indicate the R3 is the latest.

I think you are correct on this. I checked out the website and the R3 is what matches his pictures and description.

My major concern would be that mesh heat sink melting the wiring inside the bucket.
Also in their description is says that both LED's are illuminated for high beam operation. I would find that a bit odd because as far as I know the high and low beams are on different circuits.
