55 Watt HID kits

[Gunzz]

I have done a search and have not found anyone posts about the 55 watt bi-HID conversion kits installed in their trucks. I see alot about the 35 watt versions but nothing specific to the 55 watt models. If anyone has done it, or if anyone has knowledge of the headlight circuit maybe you can help me with a question.

Regular stock headlights in our H2 are said to use 8 to 15 amps when in use. The 55 watt conversion HID kits with the digital ballasts are said to use about 6 amps however they can use up to 20 amps for initial startup. My question is will the stock wiring and headlight switch handle this initial power demand or is it necessary to use the additional relay kits? Manufacturer says it's ok without the relay and it is plug and play, however want to check with others first before I listen to them and fry the wiring or switch.
