Sandonled H4 9003 HB2 high low led headlight bulb fog driving light 6000lm 3000k 4300k 6000k cool white super bright colors 3 in all in oen conversion kit halogen headlight replacement 2pcs

I bought this pair of h4 but seems that beam pattern on the left side its smaller than the one on the right on the 6k mode and on the other two modes there equal hi beams there equal to just on low beam

They work great in that they are very bright and have a nice color to them. The slim design of the cooling fans helps greatly if you have don't have a lot of room behind your headlight housing. They fit perfectly in my Silverado. I would definitely buy these again and highly recommend them. The price is excellent as well.

Excellent LED kit, way better than halogen bulbs. it’s a good touch that it includes filters to change the color of the light.

Very bright, made a huge difference in my RV. No flickering, just great white light. With the old LEDs, I had to use 3 lights in my dinette area - now 1 is more than enough. I will update after some time has passed - I hope these bulbs last.

These are perfect for my needs. Quality product, packaging, with built-in CANBUS load resistors. Very bright - great for DRL, or parking light, reverse lights, etc. Maybe a bit bright for interior use like map lights, 

I own these Lights for 7 days now and love them so much. I bought these in store near my office, they are brighter than the old one, the white light makes easier to see. I did also notice that they do produce a lot of heat but the aluminum heat sink takes care of that greatly. these are great for everyday use.
