I got an old set of off road light for free and I wanna see if they work but the bulb seems to have no ground, is this right?

the housing is the ground.

Yup. Standard H3 bulb

Yep, bulb gets it's ground through the metal lamp socket.

FYI, don't touch the glass of halogen capsules like those with your fingers, oils from your skin could cause the bulb to crack after you power it up (if you've already touched it, clean it off good with some window cleaner/rubbing alcohol, etc. before you reinstall it in the housing).

Some cheap H3 lights like the oes I bought to use as my "backup lights from hell"
there is a seperate wire with a ring terminal that goes onto the bulb retaining
screw (cheap a$$ lights don't even have clips).

And typically the Kella lights I've had use a slip terminal on the steel reflector
that runs to a ground screw. Sometimes this grounds through the lamp housing
mount (unreliable) sometimes it's longer and you ground it via a two wire hook-up
(much more reliable)
