Title: A bulb that finally lasts in my PIAA 510's
Review: Finally! An H3 bulb that actually doesn't burn out in a week! I run these now in my PIAA 510 fog lights in my steel plate bumper because I can off-road for hours and the filaments in these last and last. I've tried 3 other types of H3's and the Philips were the worst. One set lasted only one off-road trip of an hour and the filaments broke in them. It's a big pain to get the housing for my fog lights out of my bumper, so you can imagine my frustration.These bulbs have been in my fog lamps for 3 months now and both are burning bright and strong after 4 long-range off-roading trips. I run them day and night, and will be using these exact same bulbs as replacements when they finally give out.
