Review on Upgrade Your Car Lights With SEALIGHT L2 9007/HB5 LED Bulbs: 24000LM, 800% Brightness, 6000K Cool White, Turbo Fan, Pack Of 2 by David Lusk

These LED bulbs are much brighter and clearer than conventional bulbs, and use less energy than both incandescent and halogen bulbs.A few notes about the H4 bulbs:1) This is a pack of two bulbs.2) 6000K is the color temperature these bulbs are said to have, not the lumens., so don't get confused. I don't know how many lumens each puts out, as it's not given in the information included with the bulbs; but the current amazon listing claims 4000 lumens.3) Each bulb has a wire coming off of it, with a plug. So, your car's wiring harness connects to that plug, not directly to the bulb. There should be plenty of room in all vehicles, even motorcycle headlight enclosures, to fit the wire. Small zip ties are included, to help with wire management, if needed.4) Read the included instructions for installation. Instead of connecting the bulb directly into the headlight enclosure, take the collar off of the bulb (twist/click to loosen, then it slides off), and lock the collar into the enclosure. Then, just slide the bulb into the collar, and twist-click it to lock it back into the collar.* Note: The tabs on the bulb housing (and slots in the collar) are different sizes; so if the bulb's not sliding back into the collar easily, turn it 180 degrees and try again.5) There are directional reflectors on the bulb stems. This shouldn't be an issue, since the different-sized tabs on the bulb housing only allow it to fit into the collar one way. Still, make sure that your headlight beams work properly (directionally correct), once installed.
