The shop said my head light fluid was low, and wanted to charge me $50 to refill it.?

I sincerely hope this is a joke(har har har). There is no such thing as head light fluid.

Yup !

I laugh Haw, Haw, Haw........ : > ))

Now I have thought about it, some cars have wiper blades on the headlights, with a washer sprayer, to clean off the headlight lenses. However, the fluid supply should come from the same tank that supplies your windshield washer. I don't think there is a separate tank for the headlights. And you use windshield washer fluid, not headlight washer fluid.

You have to remove the bulbs and fill the lenses. Make sure you use quality headlight fluid.

Just in case u r 4 real,u have been had, no light uses liquid,some DO use gases such as neon.

well headlight fluid doesnt exist. think about what your headlights are and why would they need a fluid??? so its a scam and or joke
