ADVmonster H4 R3 LED Headlight

[olekzap_imp]

Do you need me to change the title?

Looks like i mixed up "H4" and "R3" in my title. Feel free to change and sorry for the confusion.

Glad to report that my fingers have thawed out enough to type this, and I think I'll be reading the grip heater thread shortly hereafter.

For now, I'll go ahead and confirm that this new H4 is a pretty good product. I'm astonished, actually. The light is so much brighter than the stock bulb, that I don't think I could ever go back to the normal H4 again. As others have done, I'll wrap this up and tuck it somewhere under the seat for backup, but if these things have anywhere near the expected lifespan as advertised, I don't foresee the need to ever replace it. It really is neat to see how much light reflects back from stop signs and speed limit posts, etc. It's incredible that so much light can come from that little tiny diode, no larger than the O on our keyboards.

I was looking at the stock H4 lamp, and I'm beginning to see why they designed this new R3 so differently from the others. As with the stock, most common H4s have the low beam placed directly above the aforementioned reflector cup, which would seem to direct the light upwards into the bucket. For the high beam, the filament is below, which is just where they moved to secondary LED. This seems to mimic an incandescent bulb as much as possible, with the only difference being a much brighter, whiter light. It really is a phenomenal difference.

I'm a bit surprised that others have recommended to go out to an empty road and adjust for the "high" beam. I would think this would be a better time to adjust for the "low" beam, as that's what seems to matters most. Once the regular beam is adjusted properly, who cares how high the secondary beam shines; the higher and further-ahead, the better it would seem. My main concern on the low beam is to extend every courtesy to other, oncoming drivers. If the directed beam is shining no higher than the bottom of their necks, I think the low beam is adjusted quite properly. I'm still fiddling with it a bit, but I think I have it just about right, and it still gives me about 50 feet of well-lit area beyond my front wheel. I'm not sure what the previous owner did, if anything, but I've actually had to rotate the bucket oh-so-slightly upwards to achieve this.

I'll likely report again as time goes on, but for now, I am one happy, rosy-cheeked cold customer.

I'm surprised you had to rotate the headlight up, actually. I had to move mine down and it feels like it's as far down as it will go. I was trying to get the cutoff just below the back window on a Civic in my garage since they will be one of the lower cars on the road. It's pretty close but the cutoff still seems high when riding. I can see it bouncing in reflective signs when I go over bumps. Nobody has flashed me though and I've stood out in front of it at night and it's not blinding at all. Probably just the difference in the location of the light source within the bucket. It's not perfect but it's far better than stock.

Also, did you put the rubber boot back on? I forgot when I installed mine and not sure if it's worth the effort to open it back up and put it on with the LED assembly itself being waterproof.

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 mixed up the revisions in my title. Here is the one we have ordered. Sorry about that.
