Leds won't flash - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I've had the rear leds and side marker leds for some time but today I tried yellow 1157 leds in the front and now none of the lights will flash if the parking lights or headlights are on. I have an electronic flasher and checked all the grounds. I know that the leds don't draw as much current and if I put incandescent bulbs back in the front turn/parking everything works- but I would like to use leds all around. Isn't there something in the newer cars and trucks they use when there are leds all around?
Thanks much!
