I lost the low beam on the right side on my 280Z. Both Hi beams work tho. I checked the wiring using a test light and the circuits seem to be good, so I checked the lamp itself via the connector behind the rad support. the VOM shows (continuity) meaning that the filaments are good.

My lamps are the Koito type, do those have filaments? I can look thgrough the glass, and I don't see any filaments, just some things that look like a ball on a stick?

BTW, I bought some halogen lamps from the NAPA to install, assuming my one lamp was out, and the book says it's got MORE candellas, with LESS wattage!

thx

I would say if the test light shows that the circuit is good then even if you have continuity in the bulb, the bulb is probably bad. All the test shows is contunuity, but it doesn't show the strength of it.

Yeah, since I don't know exactly what's going on inside the lamp, andit's not a filament-type, I could only speculate. It would probably be good to install new lamps, anyway. IF I can get inside there. The inner liners are pretty fragile, and 'glued' in with undercoating.

thx
