Fog lights not working with new bulbs

[LPG-over-diesel]

Hi all, I bought some new SMD LED fog lights for my 01 Leon to match the HiD conversion, my fogs work with normal H3 bulbs but when I put the new ones in they wont come on, I have a spare 12v battery so I hooked it up and tried the new SMD bulbs and they work fine that way, I'm not sure if its an earth problem or something else I hope someone can point me in the right direction.

Here's a link to youtube so you can see the SMD bulbs if your not sure what they are.
P.S the kid on the video is a idiot, he takes a few goes to light them up!!!!

i had a similar problem with LED side lights strange because i plugged them in 1 way and they dint work span it round and it worked.
CrAzY.

Leds only work one way, unlike a regular bulb.
But the H3 can only be plugged in one way.

I also had the same problem with H3 LED's bulbs, swapped the wires round and bob's your uncle

Call me stupid but isn't there only 1 wire, that plugs onto the end?
I noticed if you leave the fog light switch on, the normal bulbs wont come on until the metal clip touches the base of the bulb, but this doesn't work with the LED's

 

[LEE69]

You pull the earth of the bulb holder and swap the wires over so the wire off the bulb goes to the earth and the earth now gets the power.

i might look at that, i thought it might be something to do with the earth, I'll have to get it up on the old axle stands so I can see what i'm doing.

cool, thanks for the link . What have you used for the side lights ?

 

[DJ-LIAMC]

side lights came free with my HID kit and matches great.

 

[cocadave]

do you have a night time picture of these led fog lights?

 

[seantdi]

i got these led h3 bulbs before and found that you couldn't see the light from them. even in the dark they were crap. maybe it was jus the ones i had do...

 

[MarkWales]

would also like to see some pics please

 

[DJ-LIAMC]

Yea ill get some pics up asap , thb they dont give a beam of light and wont help you see better, just look like powerful sidelights. so they are just for show imo, look better than the standard yellow ones though.

 

[JamJay]

That's a shame because I use my foglights in the fog , so I need them to help me see.

pics against normal fogs

Still bright but not enough to use in a fog, Colour matches well with Hids though

you would get loads more glare off the fog too with a whiter bulb.
i notice this wids hid's.
