Spotlights

[luke28]

Just wondering is it legal and would it work to wire up spotlights to your headlights so they work normal & high beam

No, illegal.
Your lights need to dip and dim for low beam..

Fog lights are also illegal if it's not foggy...

Why would you want to do that ??

Just wire in a relay and put a switch in... does not take long and very easy to do!!!

Not legal but can be done easily. Could be good offroad to save the power from the cruddy halogen headlights.

Was just curious about it I've never done it figured it would be easy enough to wire into the head lights

Its easy enough but not exactly straight forward as you need two inputs to the spotty relay, one from lo and one from hi but they need to have blocking diodes otherwise the current will flow back to the other filament and both lo and hi will illuminate at the same time regardless of your dip switch selection

It could be done by connecting the switching side of the relay to both low beam and high beam without the use of diodes.

The switching side of a relay (terminals 85 and 86) is just a coil of wire, when current passes through this coil, a magnetic field is created that closes a set of contacts. It doesn't matter which one is positive or negative the contacts will close regardless of which way the current is flowing.

When on low beam, the low beam is positive and the high beam is negative via the high beam bulb filament.

When on high beam, the high beam is positive and the low beam becomes negative via the low beam bulb filament.

If terminal 85 was connected to low beam and terminal 86 was connected to high beam. The relay would switch on if low or high beam was on and would switch off if the headlights were turned off.

Although, I'm not sure why anyone would want to do this.

Not to sure about electrics dont wanna start blowing fuses and wrecking shit but also dont want spot lights on my bar not connected either ill get somebody to show me

Could you not just wire it straight to the batt and then you wouldn't even need your lights on at all just flick the switch and off ya go, this is how I wired up my light bar. But the spotties on my bar are wired to the headlights (hi been only).

You, by law, need a switch on all aftermarket lights.

So simple get a 3 pole switch, run one from the high circuit and the one from the low, switch to relay and a standard. Setup from there
