pmobbs Posted October 2, 2011 Share Posted October 2, 2011 Flashing brake light circuit is here . It will run both LED and filament lights but LEDs will need a resistor in series with the light. Have a PCB design if anyone wants to have a shot. P. Link to comment Share on other sites More sharing options...
dom69 Posted October 3, 2011 Share Posted October 3, 2011 just fitted high level light today, got it from halfords £15'ish and took about an hour to fit, run the cable behind the carpet in the boot and wire it in to the r/n/s light cluster. Worked out which was the brake light wire, shaved back the insulation on it and made a mechanical joint covered with some insulation tape, wired the earth to the exsisting earth point and job done Link to comment Share on other sites More sharing options...

Michael G Posted October 3, 2011 Share Posted October 3, 2011 Several mentions in this thread and elsewhere of fitting a resistor to the feed for these lights. I'm about to replace my high level brake light which has blown a few of its LED's. My understanding is that fitting a series resistor will "tone down" the power supply a bit and give some protection to the vulnerable LED's. Is this correct please? If so, what size resistor should I be fitting? I know nothing about electronics so please speak to me as to a child! Michael Link to comment Share on other sites More sharing options...
tbird Posted October 3, 2011 Share Posted October 3, 2011 I would hope that any 12v LED brake light available would have relevant resistors incorporated, there is no specific resistor, it depends on number and type of LED and how they have been wired up. if you glance over this you will see what I mean . I am presuming from what you say you are not building your lamp from scratch, you could buy a light and measure current draw, then work out the resistor required to drop voltage a couple of volts, which would make them dimmer but last a bit longer if you wanted to Tim Tim Edited by - tbird on 3 Oct 2011 21:27:04 Link to comment Share on other sites More sharing options...
Michael G Posted October 4, 2011 Share Posted October 4, 2011 Tim It's a proprietary light but it's LED's are popping after 6 months of use. Thanks for your advice, which I shall follow. Michael Link to comment Share on other sites More sharing options...

Dignity Posted November 12, 2011 Share Posted November 12, 2011 I just fitted the 48 LED light with the CC sub loom. Copied SM25T. A nice easy upgrade and only 30 quid all in Link to comment Share on other sites More sharing options...
philmorton Posted November 12, 2011 Share Posted November 12, 2011 At the risk of sounding like a numpty 😳 how do you plug the subloom into the existing wiring. I have a bought a light and it has wires without plugs. I have found under the near side rear a load of wires and plugs that obviously go to the rear brake cluster. I was thinking of buying the subloom to make life easier but not quite sure how it all hangs together. Better do a few more 😳 😳 😳 😳 Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted November 12, 2011 Share Posted November 12, 2011 You want to find the connector between the fuel tank and the side skin on the offside. Split this (squeezing the release tag) and simply plug the sub loom connectors into the two halves. Job done. Link to comment Share on other sites More sharing options...
philmorton Posted November 12, 2011 Share Posted November 12, 2011 Thanks, I was hoping it would be that simple. Link to comment Share on other sites More sharing options...
