70 Cutlass Headlights - All 4 high/low wiring

Has anyone modified and wired their headlights to where all four switch back and forth between high and low? Basically dual filament in all of them or LED/HID duals? If so, how did you wind up wiring it?

Why would you want two low beams on each side?

Adjust the beams for more light. 4 lights always on instead of two.

You'll have to change the buckets and the connectors for the hi beams.

Yeah, just use low beam parts in the high beam location. Easy peasy.

I'm talking about making all four lights aftermarket dual filament and having them all swap back and forth. So basically I'll have all low beams, hit the foot switch and then have all high beams.

Yes, I completely understand. As oldcutlass and I posted, using low beam bulbs and wiring in the high beam positions will do that.

Ok, just making sure. That isn't going to overload the relay or anything?

There is no relay. The headlights are hardwired to the switch, which contacts sizes to carry the current of the OEM headlights. Changes in current draw can overheat the switch.

Since the switch already powers 4 hi beam filaments, I doubt that's an issue.

Gotcha. I obviously need to get on AllData at work and print off a schematic lol

Especially if I swap to LEDs that won't draw the amps that halogen do.

Aighty, thanks guys!

If you manage to pull it off you are going to become a cop magnet.

It's Alabama. They're not as strict as other states.


I drove my XJ like this for 6 weeks and never even got pulled over if that tells you anything.

I have done that, Run 2 relays, 1 for low, 1 for high beams, use original wiring to switch them on.
No issues with cops, it's not like you are blinding oncoming traffic.
