Thinking about doing this! Great thread. I've been doing some research and found that the XB35 bulb sold by TRS has the best light output out of all the H1 bulbs currently available, It's light output was tested to be the same if not better than the Philips D2S, which is commonly used as an OEM bulb. The only drawback being that it puts off more UV radiation which can arguably cause damage to headlight components, e.g. projector bowls, lenses, etc...Has anyone used this bulb? If so have you noticed any degradation of headlight/projector parts? I'm leaning towards this bulb but don't want to pay $70 just to find out it is going to ruin my headlight setup in the long term.
