SEALIGHT H4 9003 LED Bulbs

WOW. Crazy bright. Took like 8 minutes to install. Take out the old bulbs and put this in. I've tried other ones with a passive heat sink but those burnt out or were waaaaaay to huge and were a pain to put on. These fit perfectly. I have an ancient 2006 Kia Rio and the headlight assembly is near completely opaque. It's a thick dirty yellow brown and I've bought everything in the universe to try to clean it with no luck. Normal bulbs can't shine through. These LEDs have no problem. I can't imagine what they look like with a clear plastic in front of them. These must have fusion reactors inside of them to produce the amount of insane lumens, which I'm guessing is about 3 suns worth.

After running an older set of HIKARI with Cree LEDs, I wanted to give something else a shot. Although these aren’t quite as bright as the HIKARIs I was using, they definitely have a more even beam pattern across the road. It’s also a nice advantage that the fan is built in forward of the plug so these things will fit with OEM dust covers; no having to cut out portions of your OEM dust cover or having to go through the headache of finding an aftermarket dust cover that will work with these. With them angled properly in my reflector housings, I haven’t had any issues with people flashing their brights at me. The light produced from these is a nice, crisp white. If you live in an area that experiences snow during the winter, these lights don’t make your headlight housings warm to the touch, so, I can only assume they won’t melt off accumulating snow and ice. Whatever, that’s an issue with every other LED headlight I’ve ever tried and the reason I have a set of KC Apollo halogens on my front bumper. Ignore the blue tint on the first picture as that’s from the blue LEDs in my parking light housings. 1st pic is cut off, 2nd is low beams, and 3rd is high beams

Bought for my 2003 Tundra, I thought they were a bit bright for low beam. It turns out that they needed an adapter. After about 15 minutes of finessing and zip tying, I had me some nice lights!Brights are suuuuuper bright (way more than factory) and the lows are also bright.

The color is just perfect. Plug and play, did not have to move, cut or add anything. I just wish they could also make H7 on the same type

Bought for my 2015Mitsubishi Mirage. These are as easy as any headlight to install. They are way brighter than original headlights. May require alignment like any other bulb, but do not require the “focus” (twisting) that some other brands do. I cannot comment on longevity yet, but most LEDs last a long time.

Took about 2 mins to install. Super bright. Just installed so hoping it last as long as other brand LED I’ve used.

Love the brightness of these and will update after a few more months of use.

way better than other led models with external cooling compact and works well
