LED Driver


Recommended Posts

I'm adding LED map reading type lights in the overhead console.  I understand a driver or current limiting resistor is required to prevent burn-out and current run-away with LED lamps.

Anyone done this or has knowledge of a driver ?

You do not need any additional components to install LED lights designed to operate as stand alone devices. Any 12v automotive LED light works without modification. If you purchase single LEDs from an electronics supplier, you need to add circuitry.

Thanks for your prompt reply.  These are stand-alone LED spots from ->

They are designed to be operated from a driver although they are 12volt.  I do have a 12volt constant current driver which operates from a 12v DC source but RS Components have discontinued the product.  So I'm now wondering if I need one at all?

My fear is if I connect direct to the 12 volt circuitry within the vehicle it'll just burn-out in short order?

I don't know the circuitry in the LED assembly or the details of their AC voltage/ LED driver. But they are likely just using a switching-type transformer. The vehicle 12vdc is better than the transformer output.****EDIT: these LEDs may not work.****. Buy one and test it or find LEDs made for generic 12vdc sources. These are easy to install, are bright and don't need any special power supply.Screenshot_20230504-130359.thumb.png.2311c59f6be3ccb106bd43581822f8a0.png
