2009 - 2014 Ford F150 - LEDs - Do Not Install Load Resistors for Hyperflashing! - I am not sure if this is posted here anywhere or not so I will post. (Mods feel free to merge or remove its this is a dupe.) I recently went down the road a full LED conversion on my 2011 F150 XLT. From the get go I was against the idea
The above indicative values of resistors are assuming 20 mA per LED as optimal. Do your own calculations for your specific LEDs. For a ready to use online calculator, use an "LED resistance calculator" instead of a voltage divider one. This one even provides the correct schematic or wiring diagram as you prefer, to wire the LEDs up.
It doesn't have to be a resistor, but that is probably the most simple way to do it. LED light bulbs have circuitry integrated into them that overcomes all these problems. Old-fashioned incandescent light bulbs (including halogen bulbs) are different. The part that lights up is made from a thin tungsten wire that glows when it gets hot.

I did not install resistors. I turned off hyperflash with Forscan - I did it by turning off the bad bulb notification. 1. Add a comment. 3. In my experience, and I've disassembled quite a few of these strings, there is indeed a resistor in one of the LEDs. Look for a slightly larger LED receptacle, almost always at the far end of the set. If you extract the LED, there will be two brass contacts and apparently no resistor.
If you look at the graph above, you can rise the voltage from 0 Volt to 1.6 Volt without resulting in noticeable current. Apply a bit more voltage and there is current and the LED lights up. We have reached the Forward Voltage which is needed to open the pn-gate. Forward Voltage (VF) for a typical red LED is 1.7 to 2.2 Volt.
