Hi Centretek, thanks for posting that.
Ok, so I'm looking at the products I linked to above, and they're all 12v strips, so that to me would suggest that I wouldn't need R2 from that diagram, is that correct?
If so, then I would just need R1 for dimming the LEDs down to " lights" level, and a diode on the "brake light" power feed.
Obviously from here I'm going to ask what diode would be needed?
R1 I could play around with until the required "dim" level is reached.
Another thing with these LED strips, it says you're able to cut them down to divisions of 3. So you can run for instance a length of 9 leds. Now, would this still produce the same light output if pluged to a 12v source as a full strip of 24 would for example?
This is where I start to get confused.
Many thanks,
Anthony
