I'm a new member. I've just installed LED bulbs in my 2006 E-350 van turn signal/park lights, and the turn signal is flashing way too fast. I got two 10 watt 15 ohm resistors, and installed them in the rear lights. It slowed down the flash rate a bit, but when I put the LED's in the front signals, it was back to flashing way too fast again. I have two questions... 1.: if I put another two resistors in the front signal lights, would it slow down the flashing rate? and... 2. Can I get resistors with a higher resistance that would slown down the flashing rate to approximately the factory setting? I would appreciate any info on these questions. Thanks. Don

 

You may have to install a heavier flasher in place of the original one.

 

Or is it the opposite effect? LEDs draw too little current. Similar to when one bulb is not working so less current is drawn and the flashers go faster.

If you put the resistors in parallel with the LEDs that would increase the current draw and slow down the flash rate. Did you parallel them?

If so, I think you would need LOWER resistance to increase the current draw back to what bulbs would draw.

Of course a bulb makes a cheap resistor. But then you're back to where you stood before switching to LEDs.
