These are pretty cool, considering the alternatives out there. Most of the LED headlights I ran into had a plug with a huge heat sync on top. I originally bought Beamtech headlights but it seemed like I would need to modify the water blocking rubber boot my car has in order to get it to fit properly and I didn't want to do that. Anyway, I'm dead ass not a shill but I thought these were pretty dope. Kind of expensive but they look WAY better than halogen. If they last 2+ years I'll be happy.Review edit on 4/29/2019 - These are still working just fine for me. I liked them so much that I bought some for my girlfriend's 2002 Rav4. I replaced them in less than 5 minutes. They fit great and look significantly better than standard halogen. I plan to take off the HIDs on my civic and add these as well.

To those who have given up installing LED headlights like me, this may be the last hope. I strongly recommend to give it a try.From a couple of my previous attempts, I learned that any LED headlights wouldn't fit my CR-V 2004 as long as they have a traditional heat sink & cable LED design. I don't want to cut the dust protection rubber cap because I may go back to the halogens.This one worked without cutting the rubber cap, thanks to the new design that achieves almost the same physical dimension as the halogen counterpart.One caveat is that holding the bulb onto the socket with a metal bracket was a little tricky. The bottom of the bulb is a little thicker than the halogens and you'll need to carefully place the metal bracket as the picture shows. Good luck!

The lights look well built. In my application it does not fit. I have a motorcycle and the clip is too small for these.

I've been through several H4 LEDs before, and this one is a game changer right here. The Body is designed in a 1:1 size factor so you won't have to worry about stick out behind the bulb causing fitment issues. Beam is decent and bright.Pictures shown are of a single bulb in an H4 conversion housing for 5" x 7" / 200mm buckets.Good:- Bright with thin and properly placed LED Chips- NO radio interference when the headlights are on- Able to fit in tighter housings with little room behind- Active Cooling Fan to keep temps lowBad:- Rear of housing isn't as deep as it should be, makes closing the clip fairly difficult depending on style.- Bulb rotation seems slightly off causing for a slightly unbalanced low beam cutoffOverall it's a really cool design that has come quite far and with some little tweaks it would be the perfect bulb. Certainly an improvement over dim halogens.

Extremely bright. I can see behind me much better now without lowering my tinted windows.
