$50 for bulbs? Outrageous. Not to mention getting to the back of the dash? No thanks.

If you know of a supplier whom sell LED bulbs that are just as bright or brighter than the stock incandescent 21w bulb, please provide a reference.

Concerning the load resistors, yes, you can use that method. However, if you want to reduce power draw (the point of LEDs), it is my understanding that you cannot achieve this with a load resistor as it will "consume" the power. In addition, using a load resistor will permanently "damage" your stock wiring.

Gaining access to the flasher is not overly complicated. If you replace the flasher you do not do any harm to your existing wiring and in the event something goes wrong, you could return the vehicle to it's original state without evidence of anything to the contrary.

If you have the time, the forum would benefit from a DIY of your experience with using load resistors.

No, LEDs have two advantageous aspects, INSTANT ON, and extreme reliability vs incandescent filaments.

, it is my understanding that you cannot achieve this with a load resistor as it will "consume" the power.

Agreed, but using resistors might be the easiest way to "fix" the flasher relay timing and/or bulb failure detection/indication.

In addition, using a load resistor will permanently "damage" your stock wiring.

Not bloody likely....Using the resistor(s) simply returns the electric current load factor, wattage, to something close, lower typically, than that of the incandescent bulb(s) you are replacing.

Gaining access to the flasher is not overly complicated. If you replace the flasher you do not do any harm to your existing wiring and in the event something goes wrong, you could return the vehicle to it's original state without evidence of anything to the contrary.

But great care must be excersized in replacing the flasher relay. First, you want to be sure and get a new SOLID STATE flasher. There are flasher relays on the aftermarket that will DAMAGE your wiring if you replace the fuse it blows repetitively.

Additionally many of the desireable solid state flasher relay now have a bulb failure detection circuit the will trigger a "FAST FLASH" (just like the old style) to alert you that a turn signal bulb has failed. If you don't have the expertise to open the solid state flasher and change the load sensing resistor to a value that is correct for the new, lower, LED bulb current load then the external resistor used to simulate the original incandescent buld current loading is the only option.

Complicated...

Many new vehicles come equipped with solid state flasher AND tail/stop light bulb failure detection. On my '01 RX300 I not only had to open up the solid state flasher relay and empirically determine (trial and error) the correct resistance for replacing the load sensing resistor, I had to do the same for three bulb failure detection circuits.

Not simple...

Unlike dual filament incandescent bulbs the tail light circuit/section of a LED bulb does not continue to draw current with the stop light circuit/section powered, illuminated. So I had to come up with a separate transistorized circuit to simulate the current draw of the LED bulb's tail light circuit/section when the bulb's stop light circuit/section was powered.

Also, can you confirm whether the original bulb you replaced had three wires or 4 wires on the wedge base (correesponding to two vs one ground which coresponds to SWAK vs regular base). Thanks.
