Hey guys,
I'm installing a high beam indicator for a street legal dune buggy. The problem I'm having is the headlight dimmer allows 4-5volts to the high beam terminal, when the switch is in the low beam position. In the high beam position, it completes the circuit to allow 12 volts. This condition causes the high beam indicator to be lit dimly when the low beams are on, and fully lit with the high beams.
I need a component that will allow current to pass only when a threshold voltage is reached (say 9-12 volts). Any ideas?? Sorry for the long post...I bolded the important stuff
Thanks for your time!!
Well, I went to Radio Shack and got some resistors for now. It lessens the light intensity of the indicator with the high beams on, but at least it doesn't illuminate with the low beams on.
If anyone has any ideas, I'd like to fix it the "right way"
Thanks!!
I'd probably try to find the source of the voltage backfeed, and isolate it with a relay. Otherwise, you may try using a relay to control the high beam indicator. Wire resistors of slightly higher resistance in series with the coil until the contacts stay open when you turn on the low beams.

My ex once told me I have a perfect face for radio.
That's an excellent idea. Thanks for the input!
