I got a set of cefiro and cear bumper lights and i wanted to replace the bulbs with the apc titan bulbs but don't know what part or mount numbers they are. Are they 1156(7506),1157,3156,or 3157, and 7740 or 7743? I know they are m4,m14 and m9 but what other name or # are they called?

 

that is basiclly it if you go to autolumination.com you can find them there or customenterprice but for the titan look i believe autolumination would be your better bet
