I didn't go though all these pages, but I did look at the LED page and see you got some of your facts 180 degrees wrong (in red).
Flasher Module Replacement.
The turn signal is controlled by a flasher module. Many vehicles use a standard-sized removable flasher module, which can be replaced by an LED flasher module, which is designed to blink at a regular speed with the lower resistance of LEDs. This method is a simple, plug-and-play fix, which should be used whenever possible due to the ease of installation. However, many newer vehicles have the flasher module built into the vehicle's BCM (computer), so it cannot be replaced.
Resistors. A universal fix for all vehicles is to add resistors to the circuit. Resistors can be connected to the turn signal power and ground to convert some of the power to heat in order to create resistance on the circuit. This makes the vehicle think a factory bulb is being used again, and will cause the turn signal to blink at a regular speed. Diode Dynamics provide 6 Ohm resistors, which is usually enough resistance to replicate one bulb. So, if you replace front and rear bulbs with LEDs, you will probably need to use a resistor on each bulb, or four total. Since resistors convert power to heat, they get hot during operation, so they should not be mounted onto any soft plastic. Resistors should be installed so that they are hanging freely, or only touching metal surfaces.
The issue with LEDs is that they don't use as MUCH power as filament bulbs. So they actually appear
to have a HIGHER
resistance - with the emphasis on the "appear
" since they are active devices, not passive ones.
The load resistors are placed in parallel
with the LED bulbs to DECREASE
(NOT create) effective resistance 'on the circuit'. Thus the lighting circuit uses as much power as the original filament bulb and fools the flasher relay/module (or the E/BCM in more modern cars) into thinking the filament is there and present and using the correct power.
If you are putting technical information on your site, it behooves you to put correct
