warning lamps for dashboard

Postby ross on Mon Oct 05, 2009 10:10 am

Anybody know where I can buy warning lamps to use on the dashboard, I've been looking around but so far have found nothing suitable.
Cheers,

The early ones can be had from most large auto electrical suppliers and the later LED ones can be had from most electronic component shops. The LED version does need a bit of circuitry.

I use superbright LED's for all my warning lights (except charging light where you have to use proper light)

Anton, there is a bit of circuitry to add and the superbright will work for charge too.

Please elaborate! Would love to know how you did it.

Hi Guys,
Thanks for the input, where do you get the superbright leds, I looked in the RS catalogue but some of the prices ar ridiculous like R500 for a single led lamp. Where can I get the leds at a reasonable price?

Any electronic store has them, just make sure to ask for some resistors that you have to wire in to use them on 12v (the store will be able give you right one)

You can go to communica (off the N1) or even better Yebo electronics in Midrand. No idea of any places closer to you.

Make sure to ask for superbrights, they cost more, about R10 a pop IIRC (or could be R5, haven't bought them in a while), while you are there pick up some LED holders, makes fitting the LED's in the dash a lot easier. You get 5 basic colours - red, green, yellow, white and blue

Thanks Anton, I'll go and have a look at Yebo, I was in Communica this morning buying some heat shrink, I had a wander round but I didn't see any lamps, maybe you have to ask for them.
Cheers,

Ross, comunica do have. Sadly one has to deal with their super incompetent counter staff to get them.

Anton, I'll have a scratch in a bit and post the diagram.(It's somewhere on the computer)

Ok, I think I understand the diagram, there are two resistors, one in series with the led and one in parallel with both the led and it's series resistor. Then there's a diode, I think, in series with all of that? But what's the oil light got to do with it? Electronics is not my strong point. Btw I asked my son about the leds, he's studying electronics at Tukkies, he says that you can get leds that are 7mm in diameter, that would be nicce.

Ross the oil light was on the diagram that Anton found. It is of no real bearing on the charge light, I do however recall that most warning lamps use a constant positive and take an earth or negative signal to turn them on.

LED's are available in a huge variety of shapes and sizes.

Hope the above helps.

It was diagram I found while googling so you can ignore the oil light bit. As LL pointed out virtually all warning lights receive a constant + via the ignition and the sensor switches the ground to turn the light on

Both my and Lauren's car's now have purdy little blue LED's for charging lights!

Thanks!!!
