Flea market lights - How do I figure out what bulbs are in them?

Just like the title says; I bought a set of off-road lights at a flea market and I need to figure out what bulbs are in them. I've googled every number I could find stamped on the housing but no luck. All I know is that they're halogen. How can I determine what wattage bulbs are in them?

Probably 55 watt. Take the bulbs to the auto parts store and buy something that looks the same.

According to the National Shooting Sports Foundation, AR-15 sporting rifles account for nearly 20% of all U.S. firearms sales.

Probably H3 bulbs......you can determine wattage by using OHMS law....voltage squared divided by resistance.

Most automotive lights are rated at 14v for their wattage.

so 14 squared / ohms = 196/ohms

simple answer: multimeter to the in and out wires, measure the resistance.
