The H1 bulbs are bright and appear to be built well. I’ve only been using them for a few days so I can’t say how long they will last. That being said, they don’t fit correctly in my car. If you are looking for an easy bulb replacement for your 2004 Acura RSX, look elsewhere. If you do, however decide to ignore my warning and forge ahead, I did eventually figure out a way to make them “work”. I said they didn’t fit correctly, not that I didn’t install them anyway. 🙂 Full disclosure, it was a huge pain and the end result was at best mediocre, bordering on sketchy so if you’re alright with that, read on. Otherwise, save yourself some time and stop reading here.Installation(ish): The bulbs technically fit the socket in the headlight, but the Acura RSX uses a plastic adapter that goes between the bulb and the electrical connector. The adapter serves 3 purposes: 1.) it has tabs for the retention spring to push against to secure the bulb, 2.) it has a round cylinder on the back to seal against the rubber headlight boot, 3.) it has connector terminals for the electrical plug. The issue is that the LED bulbs have a big heatsink on the back so I couldn’t use the factory plastic adapter plug. This meant that the retention spring didn’t hold the bulb in place unless I bent the retention spring arms inward. It also meant that the rubber boot didn’t fit so I had a choice to make. I could either return the bulbs and be sad or I could modify the boot and spring and forge my own destiny. I’m stubborn and cheap so I chose the second option. I trimmed back the rubber on the small side of the boot so it would go around the narrow end of new bulb without interfering with the retention spring. I also did that so it would still work on the stock adapter plug if I had to put normal bulbs back in someday. Then I discovered that I had to put the rubber boot on the bulb before I put it in the headlight assembly because the big heatsink on the LED bulb prevented me from putting it on afterwards. This created a secondary issue because there wasn’t very much space to work with and I had to turn the rubber boot inside out so I could reach the retention springs, bend the arms around the boot and then bend them again so they would hold the bulb in place. After an hour of fiddling around, the bulb was loosely held in place, the rubber boot loosely covered the bulb opening, and the spade terminals were loosely plugged into the electrical connector, so I guess you could say that I was loosely satisfied. Then came the sheer joy of repeating this brilliant process on the other side. Unfortunately, I don’t have pictures because there wasn’t enough room to see anything so you’ll just have to use your imagination. In the end, I like the way they look and how bright they are but I wouldn’t buy them again because they just don’t fit correctly.

Took me a little bit of fiddling to get it to have the low beams at the bottom. The Toyota Highlander’s rubber seal that covers my old bulb doesn’t fit on this without modification because the hole was too small. But it now looks good. I am dreading our Virginia state inspection, hopefully they don’t reject it.Edit: almost a year later, working great. The Virginia inspection mechanic said the bulb was fine and legal, not too bright. However, he said my old bulb was too dim and he could fail me for the mismatch, he said put that matching LED in ASAP. Now I have to figure out where I stored it. :-)Another thing that happened, my new LED low beam went dark at about 10 months. I swapped it with the other side and it worked fine. The fuse was blown. I think the little fan in the light was stopped. I saw grit in the fan, so I blew it out really good and then it was spinning fine. Not sure if that would blow the fuse or what. Replaced the fuse and all is well.Edit #2: One of my lights went dim just after a year. interesting that it did not go completely dark. Two of the six or whatever LED squares were not lit causing the whole thing to be much dimmer. That’s another advantage over incandescence, those go completely dark, while you are driving! So, I bought a new set and replaced them both. As before, I think the fan stopped spinning, but instead of blowing a fuse, it over-heated. Now I have a spare! I don’t blame the quality of the blade, I blame dirt getting into the fan. Need to figure out how to shield them from road splashes.

They don’t tell you that sometimes you have to switch from side to side with the light bulb because it puts the high and low beam in the wrong position

Fit perfectly and REALLY lights up the road! Installed on my Buddy’s motorcycle.

Used these to replace the difficult to source dual element bulbs on a 70’s/80’s Japanese mini tractor. They essentially use an overpriced 1157 style bulb that is constantly blown due to the diesel engine vibration. These LED’s have a sheet metal “adapter” that I was able to bolt to the headlight housing, then install the LED. Used a little silicone to seal the adapter to the lamp so that water should stay out.Now the little tractor has nice bright High/Low LED’s in the factory lamps and they aren’t burnt out.
