I purchased your LED Headlamps and when I have my daytime running lamps on, they flicker.

Grote's Answer

"Daytime Running lamps are often powered by a Pulse Wave Modulator (PWM), which sends a pulsing voltage to the lamps. This pulsing becomes visible with LED's because they light so instantly. There are modules available to correct this problem, but we do not offer them. See Link for more detail"
