HID Headlights tip

I may be far behind some of you, but here goes:

That ON-OFF-ON when starting your motor can shorten HID bulb life. Want to prolong the life of your pricey HID bulbs? here's my solution, only enables HID power when engine is running:

I did the same exact thing, but I made one modification: I added a second, latching relay. The first relay (triggered by the oil switch) triggers the second relay, which latches on as long as the power is on. I did this for safety: If I was riding at night and my engine quit for some reason, I didn't want my headlight to go out as soon as the oil pressure dropped!

Good point!

Alternatively a DPDT can be wired to latch.

I am electrically challenge so be nice..what's a latch and wouldn't it be easier to put a switch in the headlight circuit and just turn it off and on as you want, once the engine is running; obviously off until she running.

The purpose for the latching relay is that the lights will be off until the engine is running Once the engine starts the headlight is activated and cannot be turned off until you turn the ignition off which is good since motorcycles are required to have headlights on at all times. This way you cannot forget to turn them on but they are not on when starting the engine. There is no noticeable difference except that it doesn't turn your headlights on / off / on.

Those who say it cannot be done should try not to interrupt those who are doing it.

A latching relay is a relay that is set (ON) or reset (OFF) by the input of a pulse voltage. Pulse on pulse off. A constant voltage isn't required to maintain an on condition. Even after the input voltage is interrupted, this relay maintains its set or reset condition until it receives the next input. It is also called a keep relay. Going back a few years to my military training.

Depending on your line of work, latching relays are also called "seal in" or "memory" relays. The "latching" is done through the wiring scheme as described in the previous post. Power is "looped" through the relay so that when it is "pulsed" on, it maintains power to itself to keep a set of "normally open" contacts in the closed position and thus provide power to what ever device you are controlling, in this case, the headlight. The power to the "latch" circuit must come from a switch or another relay that can enable it to be turned off. There is nothing special about the relay itself except that it must have at least one set of "normally" open contacts (as most relays do) that are used for the "latch". 8-)

Here is a cutout to the HID circuit that works well. It does what the others say and have built their own setups. This would be for the 'challenged'. Virtually plug and play.
