| This listing is for a pair of H4 Xenon 80/100 watt replacement bulbs. These bulbs produce an even brighter, & whiter light than our regular 80/100 bulbs. When used with a Hella lamp you'll be able to see clearer and farther than you can with any other bulb. They are clearly marked on the package that they are not DOT approved, and are for off road use only. We aren't able to install these bulbs in your car through our shop. These bulbs are only sold over the counter or through our online store. The standard bulb that comes in an H4 headlamp is a 55/60. The lower number is for the wattage rating on lowbeams, and the higher number is the wattage rating for the high beams. |
