I have a 2004 vw polo classic .the left handside headlamp works but not the left it must be the bulb correct

SOURCE: i have 2003 2.5 z4,

check the socket the bulb goes into

SOURCE: right headlight not working

Look for the headlight connector to be melted or dis colored. If it is melted it can cause the headlight to not work an a new connector will need to be installed. Also check the fuse block. Some cars fuse the left and right headlights independently. It's also possible for the filament to be broken but by wiggling it to take it out and move it to the other side it can start working again temporarily

Testimonial: "It is fused for left and right, both fuses are ok, the connector looks fine and I tried a new bulb in both sides, it only worked on the left."

SOURCE: 2011 Honda CRV. Right brake light is on with headlights; hit brake, left brakelight brightens;right remains dim. Headlamps off, hit brake, only left lamp lights. Bulb works. Is it a fuse problem?

Your right brake light is fried. The fact that you see rear lights on both sides has nothing to do with the fact that the right brake light is out. Your brake lights and rear running lights are not the same bulbs. Go to Advance Auto Parts. They may even replace it for you. Not a big deal.
