Yeah I collect old ones when they are basically free
But watch out how much you pay or test them first on actual battery power not just ohm meter
I’ve found perfect spare headlights in rotten box under the seat that ohm out good
But in the decades they have been in the truck and weathered air gets in through the pins at the back
Put power to the bulb and it fills with thick white smoke as the filament burns in the air.
But for a $1 usually worth the risk for sure, I’d buy most any headlight bulb for that price.
