H3 is a single filament bulb with a PK22S base which is mostly used for the fog lights. It is a well-known fact that these lights are especially important in snowing, raining and foggy weather.
Kensun offers you upgrading the lights with the HID or LED set. HIDs produce 3 times more light, using 35% less power than halogen bulbs. Have a look at 35W and 55W kits and the wide range of color options which are available. No need to endure low visibility!
H3 HID bulbs have a power wire which comes with 2 leads (ground and power). On factory H3 headlight assemblies you may have only power socket. That is why you need to connect the positive to the socket and negative to any ground on your vehicle (there may be a spade connector from inside the headlight housing).The other option is LED Conversion kit. What is the advantage of it? First of all, this type of the bulbs is durable and tend to last longer than HIDs. The LEDs do not require special time for warming up, but are 'instant on'. One more characteristic of the LEDs is that they have small chips which cannot break.
