The lights draw a relatively large current, so it would require large diodes to handle it. Diodes in this case will waste power (approximate watts = current draw X 0.7V) so they'll get hot if the lights are on for any extended time. High beams of 110W will draw over 9A, so the diode will have will have to dissipate over 6W. Doesn't sound like much, but give it a try and see how hot that is when it's not going out as light.

If the alarm output is only on for very short periods you might get away with it. In any case, high current diodes would be necessary, the run of the mill 1N4001 1A diodes won't cut it.

the alarm out put is being used as a trigger for a relay. it should never see the high beams or the parking lights directly.

87= batt fused power

30 = lights

85 = dioed isolated alarm output

86 = groud

no sure what you understood when i said diode isolating the output.

If you go back and read the first post, you might see that the alarm output is being used directly for the parking lights. The relay you see there is one that he's ADDING for flashing the high beams in addition to the parking lights. Where are you getting this "dioed isolated alarm output" from?

Maybe you can draw it out to make it clear what you're thinking.

lets say he is using a viper alarm. the viper alamr has a white wire that flashes the parking lights.

__alarm_______

|___white light flash+__ dioede #1 -----------[relay]------- parking lights

_____________| dioede #2 -----------[ relay ] ------ high beams

so as you can see the diodes would never connect directly to either of the lights so all the volts and other stuff you pointed out dont really matter in this case.

So you're predicting it's a Viper alarm then? You can assume but you know what happens when you assume- high beam flash arm/disarm - Page 2 -- posted image.

Some alarms have an internal relay to directly drive the parking lights. In case you've never seen one, they do make those..

If the alarm output is actually a relay drive signal as you say, then you won't need any diodes at all. All you need is to just drive the two relays off the same line. Problem solved, if there really was one to begin with.

What would you suggest if the output from the alarm is a (+) output that is usually connected directly to the parking lights?

actualy two relays alone would solve the problem but i would still diode isolate just in case. the OP was having problems with the parking lights back feeding into his high beams because he failed to isolate the wire at the split. and evryone that posted answers failed to mention this including your self. what your talking about with the *assuming* is non sense clearly the viper alarm was used as an example. please we are both here give our honest opinion on how to help people who ask.

Well, I guess two pages for hooking up a parking light relay should be enough - high beam flash arm/disarm - Page 2 -- posted image.

If the OP is still around he should have enough to figure it out now.
