THIS BULB REPLACES THE BULB FOR AN H4 CONVERSION HEADLIGHT. Octane Lighting, Inc. We are located in Southern California in the United States. Product cannot be identified by product serial number.
Bulbs are not any brighter than the original style that I normally get for my 86 Chevy truck. If I was in the city they’d probably be good but I’m in the country and not really worth the price I paid for the lights plus extra bulbs because a plug broke off of one (my fault) trying leds in the lights see if work or do I trash them for different lights
