Halogen Bulbs for 6V Beetle
Can I buy a full set of bulbs - headlights, tail lights and front and rear indicators for a 1965 6 Volt Beetle. I am sure this may have been covered in previous threads but I have recently acquired a 6 Volt Beetle and don't want to convert to 12 Volts. As you can imagine - I can't go out at night and nobody can see my indicators during the daytime (lots of angry Chelsea Tractor drivers) and I am having to wind down the window and use hand signals. Any advice would be much appreciated. Chris.

It is going to be caused by voltage drop in old wiring. You can have the best bulbs in the world but if they aren't getting any volts they won't work.

This looks a good site

Found this website which looks interesting. Not read it all mind.

Thanks Clarkson and Big Al - much appreciated.

As well as the voltage drop issue there is often a problem with the old reflectors on these cars. If you look into the reflector bowl you should see a sharp reflection of yourself like looking into a mirror. If the reflection looks hazy or foggy then you won't have a good beam pattern and your headlights will be terrible no matter what wattage bulbs you use or how good your voltage is. You usually can't polish the reflectors because the silvering (it's not chrome) is very thin indeed. Replacement with new is the only real world solution to get good headlights if your reflectors have seen better days.

However if the other lights are also dim then you probably need to address the voltage issue first.

Also, if you have indicator bulbs inside sloping headlights, these can be very difficult for other drivers to see when the headlights are on. A bad idea really.

It is just possible that a P.O. replaced the bulbs with 12V ones mistakenly so worth inspecting them closely when you remove them - most bulbs will be marked with the voltage somewhere.

You might also check each light fixture's ground circuit. Clean down to bare metal, make sure the wire connector is clean. Most people usually do not consider the ground circuit taking it for granted that it is not a source of resistance. Solid grounding is as important as is positive current.

to check the wiring with a multimeter - turn them on and backprobe each lamp to see what voltage they're seeing. then check voltage from the battery + to lamp +, and lamp ground to battery -.

that'll tell you how much you're losing and whether its through the switches, earth or both.

Thanks to all for your very practical advice - I will follow up on all - Chris

Mr Whippy is correct about headlight reflectors. If they are otherwise in good condition, and you do not want to replace them. Try these I have no experience of them, but they look good. (for more, just Google "re silver headlamp reflectors"


Its not cheap, but you do keep originality.
