AndyGal Posted May 29, 2012 Share Posted May 29, 2012 What involved in this? I found a powerful LED at jaycar that will fit nicely that will apparently work at 6 volts. Iv heard you need a transformer to get the right voltage? and a regulator to keep it steady as at the moment the lights go up and down with the rev's. This is fine but I don't want to blow the expensive LED. My headlight is a 6v 25watt. I dont know anything about electrical things so all advice is welcomed. Thanks!

Valiant Posted May 29, 2012 Share Posted May 29, 2012 I'd just wire it up like your bulb. Quote Link to comment Share on other sites More sharing options...
UTERUS Posted May 29, 2012 Share Posted May 29, 2012 Do you have a product number or can you find it on the website? Then we can go from there xoxox Quote Link to comment Share on other sites More sharing options...
My name is Russell Posted May 29, 2012 Share Posted May 29, 2012 i did this to my taillight with one on them str8 plug in 12v LED bubs and hogs front bulb works way better now. will do headlight next also but have same question as yours applicable to 12v Quote Link to comment Share on other sites More sharing options...
Valiant Posted May 29, 2012 Share Posted May 29, 2012 Most LEDs are multi volt in my experience. Ask at J Car? Quote Link to comment Share on other sites More sharing options...
JoKer Posted May 29, 2012 Share Posted May 29, 2012 more +ve = brighter! iirc Quote Link to comment Share on other sites More sharing options...
keltik Posted May 30, 2012 Share Posted May 30, 2012 Posting interest in this. I need to change my front lights to LED as the new motor cant cope with 55w car bulbs anymore Got 2 nice projector lamp housings which take something that looks like a H1 bulb.... and would be keen to whack in a couple of CREE beasty LED's. Would like to limit current draw to a max of 15w per lamp. Quote Link to comment Share on other sites More sharing options...
Ned Posted May 30, 2012 Share Posted May 30, 2012 Depends on the LED. LEDs will blow up if you put too much current through them so they need to be regulated. This can be done as easy as putting the correct resistor in line with it or by building a constant current regulator. Constant current reg is the best option and depending on required power, a simple LM317 regulator and 1 resistor is all you need. If you use just a resistor, the brightness will change depending on your input voltage. With a constant current supply, it will be the same brightness across an range of input voltages.

AndyGal Posted May 30, 2012 Author Share Posted May 30, 2012 I've been to jay car and at first they thought I should build a small circuit with everything I need. That would have been fine, but they then showed me a unit that is already built, waterproofed, and heatsunk. So i need a AA0264 Power transformer AA0594 Led supply and im going to get a Z00449 Led apparently its the most powerful single Led they have can crank out 700 lumins!

keltik Posted May 30, 2012 Share Posted May 30, 2012 So since i run a 12VDC system on my scoots, whats to stop me using the LED without a transformer or supply? Quote Link to comment Share on other sites More sharing options...
AndyGal Posted May 30, 2012 Author Share Posted May 30, 2012 nothing you can buy a direct replacement from jaycar. Quote Link to comment Share on other sites More sharing options...
Yowzer Posted May 30, 2012 Share Posted May 30, 2012 Most LEDs are multi volt in my experience.Ask at J Car? NOPE Unless they have a built in regulation circuit, they will only operate on a very narrow voltage range Quote Link to comment Share on other sites More sharing options...
keltik Posted May 30, 2012 Share Posted May 30, 2012 Had a good look through my jaycar catalogue but couldnt find any bulbs to suit my housings. Might have to make something up Quote Link to comment Share on other sites More sharing options...
Ned Posted May 30, 2012 Share Posted May 30, 2012 I cant find that part for the LED on the jaycar website.... Those constant current drivers are pretty sweet. Pulled one to bits to check it out and they are quite good. You can get a different one that has brightness control too Quote Link to comment Share on other sites More sharing options...
keltik Posted May 30, 2012 Share Posted May 30, 2012 LED is ZD0449. Im thinking one of those for low beam with appropriate 700mw controller. Should give me useful light? Or i could just drop in a 35W HID kit. Guess i really should find out what sort of bulb is in there at the moment so i can calculate what wattage i can get away with.

Ned Posted May 30, 2012 Share Posted May 30, 2012 The forward voltage of those LEDs is 13.8V and the driver will need some headroom too but the datasheet doesn't tell you what it is.... Could be as low as .2V but eill likely be .6V or 1.2V but it could even be 3.2V which means you'll need that voltage above the 13.8V from the LED which could make it difficult/impossible to drive from a 12V supply. That transformer should cut it or you could use a different LED setup... Quote Link to comment Share on other sites More sharing options...
UTERUS Posted May 30, 2012 Share Posted May 30, 2012 What's this about H1 led? But yea, HID is the premier when it comes to lighting. Quote Link to comment Share on other sites More sharing options...
kicker Posted May 30, 2012 Share Posted May 30, 2012 I should do this too, the last time I took my scoot out at night people laughed at how dim my headlight was at idle lol Quote Link to comment Share on other sites More sharing options...

Yowzer Posted May 31, 2012 Share Posted May 31, 2012 Cheaper than Jaycar by a fair chunk. I wonder what my staff price on them is Quote Link to comment Share on other sites More sharing options...
