Does the upgrade for the 99 ML320 headlights actually improve visibility or just look great. Are the lights THAT much brighter than stock.<br> FYI Performance Products is 20% off until 1/31/02 on products!!(disclaimerI have no interest in the company)
i am not sure what you mean by upgrade of light. if it is just the light bulbs, then the light would be a little brighter but the light pattern wouldn't change, i.e. won't shoot any further down the road. be forewarn that brighter light usually use more wattage (unless it is real zenon)so it might melt the light post.<br> on the other hand, most users in the states want euro lights. here our lights are brighter and the pattern is spread more down the road (i guess because we rarely tailgate on the autoways).
I would recommend getting the Philips Vision Plus H7 bulbs for your ML320. My brother drives the same as you, and thinks the lights are very dim. I've used the Vision Plus bulbs on my CL230 and they're great. Only available from Europe. Use this site to order them to the States:<br>
