Got to thinking the other day, driving my late model Saab (yeah I know), that the headlites hooked thru the ignition switch was kind of a nice convenience. I don't have to remember to turn the headlites off and it gives me daytime running lights, which I happen to think is a useful feature.

So Im wondering if there is any reason not to hook up my P210 that way.

Any thoughts?

Thanks

I carry a few wires with assorted insulated males and females. You can overcome any switch failure by bypassing it with a jumper wire.

Better yet, carry some wire, terminals, and a crimping tool. These items do not weigh much or take up much space.

Actually, my brake switch is wired directly to switched 12v right now.

Bob;

I also recommend against running all the headlight current through the IGN switch...if you want DRL or just the convenience of auto shut-off, both can be simply and effectively realized with a relay slaved off the IGN switch. Yes it is another item which can fail, but properly sized, a slave relay can be expected to be quite reliable....I wouldn't think twice about including it in a circuit like this.

Cheers

I drove a 544 for a long time that had the headlights hooked up as such, and never had a problem... but I wouldn't do it directly. I don't think the switch is designed to handle that much current. You'd want to hook the lights up to a relay which in turn would be hooked to the ignition switch I'd think. And having a relay in there makes for one more thing that can potentially fail when you need your lights the most...
