Review on Hella 9007 100/80W Twin Blister High Wattage Bulbs - Powerful and Reliable - 2 Pack, 12V by Arnold Carrigan

Good. So I bought it two years ago. (80/100W bulbs) In that time I've driven about 40,000 miles, 75-80% of it in the dark. They haven't burned out yet. HOWEVER they melted my factory spark plugs two months ago. I bought a new set of spark plugs, high temperature spark plugs, and after a couple of months they melted those plugs too. Last week the passenger side headlight melted and grounded around the base. Both lights went out while driving. I only made it home because I turned on the offroad light on my car, which they gave me for playing up. I managed to get the driver's side bulb to work so I could drive until my new headlights arrived, but it only works because I cut off the connector so those bulbs melted and plugged it right into the bulb put myself. Save yourself the hassle, save your headache and save your car. If you need a brighter light, spend the extra $30-$50 and buy LEDs. I would like to have.
