I was just pointing out a resister would be needed for LED light replacements. Don't disagree that the backup lights could use some help in how they direct their light.

Lights under the back bumper would help but it would have to be a bright white or amber color to see the road..

OK, after some experimenting with 2 different types of led reverse lamps from superbrightleds.com, #'s PT-WHP10, the one I ended up using, and RT-W24, the square one:

I taped them up on the bumper in various locations to see how well they worked. The square ones definitely are brighter, but I could not really find a good location where they both worked and lit up the right area. I did find out that the closer to the corner of the car the better. The rectangular ones are not quite as bright, but do the job. I considered cutting them into the black part of the bumper, but rejected that idea. I really did not want to drill any holes and to make the car completely restorable to original. It is best to remove the tail light assembly in order to pass the wires. It is very easy, just remove the electrical connector by raising the red lock, squeezing the retaining tab and removing the connector. Then just unscrew the white plastic retaining screw and remove the tail light assembly.

The led's come with 3 wires: red, white and black. The white is negative/ground and the red is positive/hot and the black is for brake lights, which may not be a bad idea to hook up, except that it would probably be illegal. I decided to pull the wires for the lights from one side to minimize the possibility of messing something up. Once the connector is off, I used the correct wire release tool to remove the light blue with black stripe and the brown wire. Don't forget to open the secondary lock on the connector, see pic below.That is the hot and ground for the reverse lamps. I then carefully took off a bit of insulation from the wires with a razor blade and soldered the pigtails on to them. I then put a piece of shrink tubing on and replaced the connector pins.



I then ran the 2 wires for the lamps through the rubber grommet for the fuel door wire. I used White and red wires because that matches the led lamps. Feeding the wires down to the space behind the bumper is easy with the tail light assembly removed. I ran them through wire looms and secured them with pull ties.

I then looked for a place to put the lamps that would light up the area behind the car and would allow me to mount them without putting any holes in the car. I ended up using 1 existing screw on the car and fabricated up some brackets for the other side. I had a couple of old trim pieces from an old boat that I ended up using. You can use just about any light weight material for this or if you have a C&C machine you can really do it right. I decided to use the lower-inner bolt from the bumper mount. It sure wasn't very factory tight and was real easy to get out. It was then just a matter of placing the trim piece, marking it and bending it in a vice. The aluminum was real easy to shape and the brackets came out real good.





to be continued...

I Should say that I bought all of the stuff from superbrightleds.com and here is a list of what I bought:
pt-whp10 led lamp (x2)
pt-brkt bracket
gr-65 mounting grommet
pl-3r pigtail
I also bought a chrome bezel that I did not use:
kc-65 Chrome bezel
The total cost to me is around 85 dollars, not counting the installation stuff like wires and pull ties. The entire job is less than 100 dollars.



I think that it looks pretty good and it definitely lights up the area behind the car. I messured the distance from the lowest point on the car to the ground and the same from the lamps and it is only 1/2" to 3/4" lower. I will also have to be careful backing over parking curbs, but I don't go over them anyway. Well worth it and the car is much safer...Mark

This pic may make it easier to see where they are located:

So I finally got around to doing something about the abysmal backup lights.


$19 on Amazon for a pair. I put one on each car, so that's the light from one lamp.

I'll post a picture of it mounted when it thaws, but here is the light from Amazon.

I tucked it in tight to the bumper cover and attached it to the metal tab that supports the bottom lip of the bumper.

Default '14 Beetle backup lights

Here is couple of the light mounted on the car;


That's the muffler on the right and the bottom edge of the bumper cover on the left.
Almost looking into the backside of the bumper cover. I had a "L" bracket from the hardware store and drilled a hole in the metal tab that supports the bumper.

I have been looking at LED replacement bulbs and some sort of utility light under the bumper wired up to the reverse lamps. I have found some bright bulbs on Amazon. Also I picked up a LED DRL kit from Northern Tool to experiment with. I think one or both will vastly improve the situation.

Not sure about this but I signed up to ask this question, saw a TDI that had LED strips under the bumper, but the music it was playing was in sync with the lights and how it was blinking.

Similar to this Arudino setup http://bestrgbledstrips.com/2016/11/...strip-arduino/

Do you know how he did it? Is there a way to connect rgb led strips with Arudino directly to the car's audio system?

I'd like to do this with Christmas songs on my TDI. So I was wondering about his. Really all I came for lol

They sell those in audio electronics and even some parts stores now. Just a variation on the LED lights they have been selling for a while now.
