Whelen LED low power mode

[167]

I have a pair of amber PAR46 bulbs that I use as fog lights, more as a way to be seen, not to see. They're great during the day, but at night, they are too bright for oncoming drivers.

I presume that the LEDS with low power or cruise settings operate by lowering the voltage to that particular module.

My question is if that is correct and what would be the best way to accomplish that - diode?

Do you have a model#??

The voltage at the diodes remains the same when in low-power mode as when in full-power mode. Pulse-width modulation (PWM) occurs at one rate for full-power mode and at a different rate for low-power mode. Whelen holds patent US6586890B2 that may be a good place to begin your research.

If your lightheads don't have a low-power wire, you may consider connecting them to a ULF44 which will provide you with a low-power mode.

Good point cause the par46 from whelen doesn't appear to be low power type just high.

Ifbthat will work, sounds like a pretty simple solution. Thanks.
