55w hids is another progress and update in cars bulbs...
even though 55w hids are brighter than 35w hids, they tend to wash out some of the color of the HID bulb due to the light output. for example, a 55w 8000k will look similar in color to a 35w 6000k kit.
55w Kits are not recommended for smaller fog light housings because they tend to concentrate a large amount of heat in a small area.
so if you really need maximum light output to drive on very dark roads, you will want to install a 55W HID kits for more lighting power. ok , just go for it but need to be concered of the issue of melting housings or bulbs...
before that, firstly know difference between 35w hid and 55w hid kit ..
