Xenon red LED stop/tail lamp upgrade kit

Noooooooooo. Don't tell me you go out after dark. Shoot you prob even get the car wet and use the wipers.
 
Seen them in classic Mustangs. They are readily available on this side of the pond at a much better price, just google XENON STOP TAIL LED BULBS RED 1157. If you use LEDs in a blinking curcuit you may need to add resistance to make the flasher work right.

I don't drive in the rain or after dark on purpose but both have happened. You may recall that the original Whitephrog was totaled by a rear end collision a few years ago. I'm just looking for more intensity in my tail/stop lights to aid in avoiding that same occurrence in the future. I survived the first collision shaken up but otherwise unscathed. Want to increase my odds a bit more.
 
I don't know about this specific set, but LED bulbs have been tried. The "regular" direct replacements (those that fit) don't draw enough current. Here's why. The stock Lucas flasher unit is made with a bimetal strip. Think of the coil you've seen inside old mercury style thermostats. In our case, as current flows, the strip heats up. As it heats it bends because of the difference in the metal of the two sides. That causes it to break the electrical connection and your bulbs go out. The strip cools, contact is made again, current flows, and it breaks again. That's how you know you have a burned out bulb. The light on the dash never goes out, because not enough current is being drawn to make the process function. .. LED bulbs cause the same problem. You can replace the flasher with a modern one though and then you'll be just fine.
 
Check the orintation of the bulb socket that your going to use. 1157's shine in all directions those are kind of like a flashlight concentrated beam.

I did it, got them from a website called superbrightleds.com This site is great because you can get full mechanical drawings and specs of the bulbs to be sure that they will fit your application.

I did change out the flashers for the new fangled ones. In a 79, you have two flashers.... one for the turn signals and another for the hazzard.
