The passenger side bulb went out. Now the only way it turns on is if i have high beams on. Do i need to buy a whole new headlight? If so where can i get one? Its for a 66 valiant
 
Yes the low beam element burned out. Napa can get them still. You might want to change both so they are the same brightness if you drive at night.
 
Any autoparts store will have replacements. This is of corse assuming you have standard bulbs not LED etc.
 
At the A-body headlight store....
Seriously though - https://www.amazon.com/dp/B000H29WN2?tag=viglink21494-20
I would probably replace the pair. If you want to make a big improvement, put in relays if not already done.
Yup!! GE's H6024NH is probably the best sealed beam you can buy new these days.

Its going to draw a little more current than the original 6012 bulbs use in '66. But your not going to find 6012 bulbs at the store. For super original, the only options are used or very old stock. If wiring is a concern, then other brand H6024 lamps draw only nominal 35 Watts on low beam (but don't light the road as well as the GE Nighthawks).
 
Make sure you are getting power to that side. The normal OEM run is usually, power to the driver side light and then a jump wire from that connector over to the pass side. Check the pass side connector with a volt meter or test light.

Otherwise the suggestion that ZKX & Mattax made on the GE light is great. I suggest that bulb for single headlight cars all the time when installing my relay kits. Make things very bright!

Another unbelievable !----------the op !
 
Using the stock feed to a relay that is wired directly to running voltage (~13.5) will make those halogen headlights ~25% brighter than harness fed. Check your pigtail voltage at idle and then check your hot off the alternator or battery +.

hey we all started somewhere. Most of us that was knowing little to nothing, whether we knew it or not.
I remember taking a headlamp into the parts store to get a replacement pair. The guy says, both lamps? are you sure its blown? Uh, well, uh, no I guess not. (I didn't own a Simson and certainly not Fluke or any other multimeter) The lamp I brought in tests fine. H'm. Go home and try the other lamp using the battery charger. Lights up. Wasn't the lamps at all - circuit breaker (yes, a'75 Valiant). Lesson learned because the store owners were helpful even to a dumass kid.

@Valsig66 Pishta makes a good point. The less resistance in the electric lines equals more voltage at lamps, and the brighter they will burn. If you want to walk through how to test, people here can help you do that. If you want a plug-in version of the relay setup that Pishta shows in the diagram. Rob (crackedback) makes a good quality one.
