You shouldn't have to go with an electronic flasher if you install resistors inline when you install your LED's for the turn signals, and brake lights.
This is why in most newer vehicles that have a bulb out warning on the dash that comes on if your not using the resistors. The LED's are using so little power the vehicle thinks that it's a blown bulb.
If your using resistors, the truck thinks there's a regular bulb installed.

Using resistors defeats the purpose of Led’s Which as you stated they draw very low amperage. I use an electronic flasher and like it. It blinks the same where I have just the truck or a trailer on with twice as many turn signal bulbs. They are not expensive.

I was assuming he was going with the LED's for looks and output not to minimize load on the circuit being that it wasn't stated in the OP post. I wasn't knocking the electronic flasher just putting the option out there.

I already have a heavy duty electronic flasher to correct fast flashing when a trailer is hooked up.
I'm going with LED for looks, brightness / safety, and low power draw.
I'm not interested in adding resisters if possible. Don't want to hack wiring either.

Agreed. Hopefully it's that simple. I'll find out pretty soon.

This may be a helpful video for those of you with questions about LED turn signal replacements & resistor installation:
LEDs generate significantly less resistance than incandescent bulbs. The flasher relay goes into hyperflash mode to let you know when it's time to change the bulb. This is due to the fact that filament bulbs wear down over time, which produces less resistance in the circuit, and triggers hyperflash.
Adding resistors or changing the flasher relay module (when applicable) will add the necessary load into the circuit to prevent the flasher from going into the hyperflash failure mode.
Hyperflash isn't going to cause any issues, or make your bulbs fail, but most people prefer the normal blink rate.
Hope this helps!!
Thank you,

Before you make changes to your lighting, please consider the regulations. FMVSS108 to be exact.

Simply exchanging LED bulbs for the incandescents that the housings were designed for is a guarantee of poor performance. Maybe have a read at Daniel Stern's page.

I guess that's why I haven't had any issues

I'm just going to be replacing the bulbs. I hate the look of all the aftermarket ugly tail lights.
