Fitted some flexible red LEDs on the back

I saw these flexible waterproof LED strips and bought some red ones for the rear and some white ones for the front.
Fitted the rear ones on Lurch so far.
Really ought to do the front ones as well, maybe at the weekend...

You can never have too much bling

My rear lights seem to get rather caked in mud and then can hardly be seen, so not just for the bling effect!

John - only one of your number plates lights is working.

Gidday all,
For someone on this side of the world to tell someone on the other side of the world that his number plate light is not working, just cracked me up. It has made my day, but mind you I have got a warped sense of humour. What a classic.
Regards Rick.

That number plate light started strobing whilst I was testing the wiring and by the time I came to take the picture, it had stopped working.
This seems to be a big problem with LED lights and the Haflinger. Maybe because the electrical output varies quite a lot.
Like Gary, I only noticed it when I posted the photograph!So will hve to check the connections and replace it if necessary.

Did you put any sort of resistor in?
I was just reading an article about replacing G wagon switch lights with LEDs and LED life without a resistor can be extremely short esp when replacing old incandescent bulbs.

My understanding is that with indicators a resistance is required to trip the coil in the Flasher unit of
the indicator circuit.
With all other 12V LEDs, a 12V supply will suffice ( although most modern alternators chuck our 14.4V but in the remit for "12"v LEDs) and he need for resistors is unnecessary?

No, no other resistor except the ones that are already part of the unit along with their own voltage regulator chips.
If you want to use LEDs as indicator bulb, you either need to put a resistor in because the old style indicator flasher unit rely on a bi-metalic strip which is heated by the current flowing through a coil of wire and the LED's don't provide enough current. You can get new electronic flasher units which don't need the current draw to work.
Ordinary LED single light units might not have a built in resistor but most new vehicle (12 volt / 24 volt) LED's already have a voltage / current regulator. The biggest problem seems to be that the built in systems are not as good as they should be!
I am toying with the idea of using a big capacitor as used by the Audio fraternity when putting in high power Amps in order to even out the electrical power delivery.
