I don't want to do this if they are not as bright or don't evenly fill the reflective area. If they need resistors, how hard are they to install.
My only electrical expertise is taking an old bulb out and placing a new one in.
Thanks for you input
Just installing the "45 High Power LED 1157" WOULD result in your "bulb out" warning indicator to illuminate UNLESS you used a bulb with the load resistor built in, or installed your own additional Load Resistor OR you disable the Bulb Out system...
I chose to disable the bulb out system...

Keep this in mind... If you replace a bulb with an LED and install the Load restsor for that bulb, the Bulb Out warning system will never tell you if that LED has blown anyway... So assuming you are going to replace all or most lights with LEDs, then you have effectively bypassed the entire system, you just did it by wiring in a LOT of extra load resistors as opposed to a simple disable of the system at the source....
Unfortunately disabling that system works for ALL lights EXCEPT the blinkers. For this reason, I used the blinker bulbs with the load resistor already built in. VERY pricey but kept me from having to worry about any load resistors myself.
I went with the more expensive ones for the back up bulbs, not because of the load resistor being built in to those, but simply because they were the brightest / highest wattage I could find. They do make the 1157 type bulbs that I used for the brake lights, in a white version that would probably work well for the tail lights. They would probably be brighter than the stock ones but I wasnt sure if they would give me the light WHERE I needed it. I wanted to make sure the light was a bit more focused than what normally comes from the LED tower bulbs, and besides, to me, you cant get TOO bright on back-up bulbs so I just went straight to the brightest I could find.
Super Bright LEDs actually have an option very similar than the one I got from JDM....
