3Racing led light set

[beetleman]

Hi all,

I just purchased my second 3Racing led light set as I was so pleased with it on my Tundra. I'm referring to the ingenious and stupidly cheap system that blinks according to steering and has functioning brake lights and even a backup light, all responsive to the transmitter. My question is can I add another pair of leds to the blinking ones? As there is only one socket for right blinkers and one for left, obviously I can't plug in additional pairs. So I was thinking of cutting and joining wires.

But I'm afraid that if I do so in parallel, I may damage the unit as 2 pairs require twice the current from one socket? And if I do so in series, I'm guessing the brightness will be reduced in half? Or do leds require so little power that this won't be a problem? I'm totally guessing here as I do not have experience with leds. Please help!

Thank you!

A lot of views but not a single reply... So no one knows this set or has experience with leds?

Any comments will be appreciated.

Thanks guys

hi there i would run them in series if i where you , also what are you using the additional winkers for ?

if you are usin them as side repeaters you could use optical fibres?

doubling LEDs in parallel will halve their resistance

but will still be lower than the current limiter in the unit.

Should be ok.

Running LEDs in series does dim them slightly due to

halved voltage across each one, but brightness of LEDs

aren't straight-line proportional to input V.

You could also replace existing LED with 2 of higher brightness,

you can buy fancy 5mm LEDs that output 30,000mCd vs

normal LED of 2,000mCd with both drawing same current.

Thanks guys for the replies.

I want to use them on my Wrangler and have blinkers both in the front and sides (I saw that's how it works on 1:1).

So if I understand correctly I can use another pair in parallel and it will work? WillyChang - how do you know about the current limiter of the unit? Is there a spec I overlooked?

LEDs usually run at 20-50mA so they'll build in the resistors on the PCB.

Have got the 3racing kit but don't remember how they're wired up.

Last surgery I did was on YeahRacing Dark Drifter set; that's got each

LED wired individually back to the board (so 4 wires for 2 LEDs).

They're all connected to same PCB tracks anyway so I CBF'd

splicing 4 wires... cut the 4 into 2 and ran it all the way back

to run 4 brake LEDs in the cups.

LEDs are safe to rewire, each is just about a deadshort across them anyway

so you can't really do much worse than that. Just watch their polarities.

Usually more casualties with the input voltage to those control boxes;

they don't live long when fed 7.2V vs 6.0V somehow.
