H4 is a twin filament bulb used for the high and low beams (2002-2007 Suzuki Aerio Sedan and 2014-2017 Toyota Tundra).

You cannot see further than the headlights and you can do the whole trip that way. But there is no need to put up with this. Discover the advantage of night visibility with Kensun Conversion kits.

When looking at H4 HID Kensun kit you will find out that there are several available types of them. Single beam H4 HID kit performs for the one beam and can be installed to the high or low beams on the vehicle. The other options are dual beam kits: Low Xenon/High Halogen and Bi-Xenon. You will replace both high and low beams installing one of these kits. Low Xenon/High Halogen kit will provide you with the Xenon lights on the dims while the brights will be just the same as your OEM halogen bulbs. Installing a Bi-Xenon kit you are upgrading high and low beams to Xenon lights.

All these three types of the kits are available in different wattage (35W and 55W) and colors.

If you are not a HID stickler, Kensun has LED kits for you. You can find LEDs with Cree Chips. These lights are brighter than OEM halogens and last longer. One of the most interesting features of this kit is that it comes with the pair of color filters so you can experiment with color output and find the favorite one.

The other option for LED lovers is a kit with ETI Chips. Owing to its newest design, the light emits through 360◦ so you can forget about the issue with dark spots and short beams on the road.
