Why are the high beams on my car not working?
If the high beams function but don’t seem to light your way, especially if you drive an older vehicle with polycarbonate headlight lenses, your car may be a victim of headlight fogging.

Do you need high beams or low beams?
Low beams are the bare minimum, for safety’s sake, but high beams are an absolute must for night driving over 25 mph. For most vehicles, headlights are a basic electrical system, controlled by switches and relays to turn them on and off.
What to do if both low beam headlights are dead?
If you don’t have a way to test the low beam circuit (you can probably see a missing/blown filiment) bulbs for continuity do you buy a switch for $$ which will be hard to change & you usually can’t return if its not the problem OR do you buy one bulb and swap it which is cheap & easy ?

What’s the difference between low beams and high beams?
Many vehicles on the road today have halogen headlight bulbs with two filaments. One is for the normal low beam headlights and the other for the high beams. Other models might have two separate headlight bulbs. Since the low beams are used the most, they tend to burn our much sooner than the high beams.
