LED lights
wondering what type of lights the turn signals are, tail light bulbs and reverse bulbs. plan on replacing all of them with super bright led style sight called superbrightleds.com which bulbs on there would replace all the one on our trucks.

If you go to this site they have the LED bulbs by vehicle listed Recon Accessories: Home or OSRAM SYLVANIA - Automotive Lighting and look up your truck. The Sylvania site will have every bulb to include dash and interior lighting so it's a better resource to use.

Make sure that you also get load simulating resistors and/or a heavy duty flasher. The brake lights and signal lights run on biased circuits, which means if they don't draw enough current, the bias voltage remains. The system uses this to detect burnt out bulbs. The turn signals will flash fast, and the brake lights can send flash signals to the ECU. You can use either a new flasher that ignores the bias for the turn signals, most heavy duty flashers are of this type. For the brakes, you must use the resistors. You may not notice any apparent problems from not running the resistors, but I made the mistake of not using the resistors. The computer could not distinguish between the brakes on and the bias voltage. The computer interpreted this as the brakes were always on, and it cost me a transmission.

i run ebay tower LED's front and rear (3157 size by the way), and only a replacement electronic flasher; been this way for 3 1/2 years with no problems.
here is a low-quality video clip of a rear bulb:

That was a pretty clear, and cool I might add, video. Those eBay bulbs had on part number? Just curious in case the OP might try to find the same thing on superbrightleds.com.

Same places you get the lights. If they do not sell resistors, don't buy lights from them either.

I replaced my flasher with an actual LED flasher for F-Series trucks. Offered by Trucklite #97283. I didn't know until I took the old one out that it was not a standard 2 prong flasher but was a 5 prong flasher.
