Bought me a 1999 ram 5.9 to haul with and i need to replace a low beam in these aftermarket headlights to get it inspected. New member and i was hoping someone here could help me with what kind of bulb these aftermarkets take and how to get them out. Text on lights says SONAR SK3302 RAM94

 

If the harness/bulb socket hasn't been cut or changed the bulb should be the same as a stock replacement. My 01 has a 4 head light system, the low beam stock replacement is a 9007. Look under the hood behind the lights and you'll see. I have stock capsules and just changed the bulbs from under the hood. The one behind the battery is a little tough but can be done.
