how to tell if a led is blown ?

[red6n2]

how do you know when an led light is blown... ?

i was driving and i closed my sunroof and then the interior light flashed... shat myself at first as i thought it was a speedcamera... but when i got home and opened the door my interior light wouldnt come on... cost me like 13 quid from ultra led's too..

a blown LED should smell like f*uck ... it really smells bad

LED's rarely blow,it's normally down to cheap circuitry.If you got it from ultra LED's im curious as to what one you bought.Mine was from there and was about £4.50 posted i think.

To check it's blown take it out out stick it on a 12v battery thats the easiest way,try it in both directions as essentially being a diode LED's are polarity contious.

ive had some LED's in my room for a long time now i keep meaning to fit them iw as just wondering how you get to the unit is it threw the engine bay? orr? and does the LED just plug in or does it need soldering in or anything?

[red6n2]

sooo it possibly just my interior light has gone balls up ?... damn

its flashed then flickered then went off completely... i didnt notice any smell

polarity... what now ? lol.. i know absolutely nothing of electrics only very basics that plumbers need to know

i did have a quick look at the fuses but im not entirley sure wich fuse it is and the ones i checked were ok.

Odd the fuse has blown considering how little power the LEDs use...might suggest you have a short to earth somewhere.
