        Use a low temperature soldering iron with pencil tip. Make sure your pencil tip is in good condition and pre-tinned. You should only hold the tip onto the solder less than 10 seconds to get it to melt.

          Just did this and was able to swap the light bar out with the OBC still in the dash.

          By cutting the bridge and laying the LEDs flat, I must say it looks very stock. I was expecting it to be more bright. I'm glad it is not. Same brightness as my original radio.

          Thank you.

            Do you have to use yellow LEDs?

              No, you can use clear LEDs as well.

                Hi Guys.

                I have noticed my OBC's that use LEDS have a bright orange colour on the lettering on the display, while the ones that use Bulbs have a Red colour.

                Just wondering is there anyway to get a Red colour using LEDS, or do I have to use incandescent bulbs to get that original red appearance?

                  EuroCCA link is dead. I have completed two of these bars per the link below and neither works. Any help?

                    Figured it out: wiring in the RTS link above bridges the negative leads. I did not bridge, but instead soldered the cathode lead into the hole hidden under the resistor, so that the anode (+) and cathode (-) leads in the second pic are soldered as marked (without the bridge). Same result.

                      Agreed RTS is a horrible write up and did not cover the bridging of the negative side.
