Help please New undertail Led problem

[Dafe]

If your LED's are two leg inputs only, something similar to the following diagram is probably whats being used.

Thinking about it, I should have made R1 & R2 both 1200 ohm.
If you don't understand the circuit operation, just ask.

My brain is running slow today, i have a cold...so forgive the silly questions - but did you buy LED bulbs that fit into standard bulb holders, or did you get an undertail assembly that has LED light built in and wires coming from them for you to connect.... ?

Hi allun

This one
An undertail assembly that has LED light built in and wires coming from them for you to connect.

Sounds easy, but I am starting to get the picture now

sory dude instructions went with it...ill email the guy i sold it to see if he can help.

Great that would help

Thanks

So does that mean that the LED is a light only type bulb (no brake light capability) or does it mean that I am missing something?
i would say yes and yes.

I thought about ringing you mate now I know why I didn't

The light emitted while on headlight mode is bright as... that is as bright as the LEDs are rated. When you activate the brake you cannot see any difference cause they cant get any "brighter" than they already are. So as was mentioned you need to put a resistor in the park light circuit to dim that one down a bit so when you brake the full brightness is acheived.



Just read that .. bloody terrible, but you prolly get the picture.

Thanks mate.

Yep the picture is getting clearer thanks

Thanks for your input Dafe and the diagram nice

It is all starting to make sense.

Thanks for your help everybody.

I would hook the park lights up to same as tail light, then hook brake up to what is currently park. Just my opinion

Errr would this work? without endangering the LEDs

I would put the original back on and your problem would be solved

Nice

I am very close to solving the said problem :spudwave: and it is all looking very tidy indeed.

you could have just texted.

All sorted, thanks for all the input

Here it is all installed and happy

Go on have a look






New detector





Cheers every one
