Review: Clear and colourful - So, story time... bought myself some COB LED sidelights for my lil RAV4, put them in and were beautiful blue, my OG headlight bulbs.. noticeable not. So researched as much as i could for both legality, Kelvin measures and good quality bulbs that also have a noticeable blue/white tint to match my sidelights. Came across these! Personally i love them, they give the exact look i was after. For on the road in my opinion they work very well. Going from OG halos to these i feel a little more comfortable and confident in dark conditions. I also tried them in rain, i can say a little lacking in heavy rain but not enough to say unusable. (Could also help that i have bumper mounted fog lights to increase visibility) but over all im very impressed, the style, the quality and the road use. For anyone whos concerned about "off road use" i wouldn't worry, as long as your lights are adjusted/angled appropriately (i.e. not pointing AT other drivers) your fine. In the UK headlights can go upto 6000K before being questionable. Also, for anyone not aware DO NOT touch the bulbs with your bare hands.
Review: Crisp white light! Close to HIDs - If you are looking for white bulbs then these are the ones! This is the closest you are going to get to HIDs withought fitting any. They have a slight electric blue feel ontop of the white but not enough blue for them to be over white. They are bright too, as long as you have clean lenses and level your headlights correctly you shouldn't have any issue with these. I currently have these sitting in a clio mk 2 ph 2 with reflector headlights and have had no problems, no flashes and they don't look garish and dazzling out the front, just crisp white light! Tried to write a detailed review as best I could as usually people don't make it easy buying bulbs online. Get a set for yourself and see!

If you are looking for white bulbs then these are the ones! This is the closest you are going to get to HIDs withought fitting any. They have a slight electric blue feel ontop of the white but not enough blue for them to be over white. They are bright too, as long as you have clean lenses and level your headlights correctly you shouldn't have any issue with these.

### ⭐⭐⭐⭐ Definitely better than the standard 55W
*by P***P on 2 February 2024*

I bought a set of 2 H7 80W bulbs, they are definitely better than the standard 55W ones, but the light beam is not as strong as I would expect, considering the power difference. The color of the light, compared to the Osram Original bulbs that I had previously installed, is completely white, even with slight blue discoloration. I satisfied with the product (for this price), but for off-road riding I would look for bulbs with a slightly higher power.
