HellaH71070227 Optilux XB Series H1 Xenon White Halogen Bulbs, 12V 100W, 2 Pack

I bought these bulbs to use as high beams on an aftermarket HID projector kit I bought for my truck (the high beams on that particular model are halogen and are not projector). These are exactly what I expected and well worth the $14 I spent on them. They are about as bright as a standard 65W high beam bulb. I say this because they are 100W (brighter) but they use a blue tint (which reduced light output) to reduce the yellow in the light and make them appear whiter. The result is a bulb which is about the same brighness, whiter, and a much shorter lifespan. I highly recommend carrying spares of these bulbs if you don't want a ticket for driving with a headlight out. Also, while they are much whiter than regular halogen bulbs, they are not as white as my 6000k HIDs (which I also expected). All in all, I got exactly what I expected plus spares for what I consider a very resonable price. For that reason I give these five stars.

UPDATE:Less than 1 month since purchase and installation, the bulbs are pretty much useless at this point. I decided to take them out to inspect the condition and was a little surprised how poor the condition that they were in. The bulbs were still illuminating but not very well. It looks like the yellow paint/coating that they use has burnt completely. See images. Not very pleased and wondering if these can still be returned. Total waste of money.Finally got to use these in the dark and they're don't really do much. Not very bright and definitely not yellow, they're more orange than yellow. In the image, it's close to the color of my turn signal/running lights which are orange. They're also extremely hot so i caution those with plastic lenses, you could probably melt them with how how these get.

Excelente producto, muy buen precio y calidad, cumple con las especificaciones mencionadas en la piblicación, recomendado totalmente.

It’s not working after 4 months.

I bought the Xtreme Yellow Halogen bulbs and I only recommend buying this bulb for foglight only. Comes with 2 Yellow Halogen bulbs and fits only for H1 foglight. It's golden yellow and looks exactly like the GT LED golden yellow on many sports cars.When installing, do not touch the bulb glass whatsoever with your fingers as it will leave oil and prints and cause damage in the future to the light. Only touch the silver aluminum when installing it into the H1 insert slot (probably why so many people's bulb light gets burnt real quick).A side note: Be sure to test the bulb first before you clip it into your head/fog light. I know for me when I was testing my new left fog light I had to switch the other Xtreme Halogen Bulb with the other one because it didn't work and now they both work just fine. If one of the new bulb doesn't work, just switch it with the other one and it'll work. Hope this helps when testing it.And I'll keep you guys updated as well to see how long these will last and hopefully, it'll last up to 80,000 miles like it says it would on the description, but I know for a fact that I will not use my foglight much unless it's severe weather like rain, snow, ice, and dark areas. Although it is badass having the fog light on for looks on your car lol
