Hi i understand we now have a rear fog lamp for mot,what is the best way to wire light into the headlight system?, so it cant be on when lights are not on, also does the switch have to show red? cheers baldrik, its a bike trike if that is any help, thanks for any help. ;D

Hiya,
according to the MSVA manual, fog lights are optional on trikes, so I wouldn't have thought they'd be required for MOTs either. Anyone know differently?

We had to have one at our local MOT station  :P

My trike was MOT'd recently and didn't need one.

never needed one either on my old un nor my new build  ;D ;D ;D ;D

Hi all still no wiser mot not due till 2009 but would like to sort fog lamp if we get another warm day over winter, just may have to go ask my mot station, but i thought you clever persons on Manky site may be able to help how to wire etc but thanks alot cheers baldrik :o

If you have your heart set on one then wiring it up is easy.
Youll need  a switch ( illuminated )
                a standard 4 pin relay
                a fog lamp
                assorted connectors and wire
The switch, will have  3 connections
1. feed in, this needs to be connected to your dipped headlamp 12v + feed
2. feed out, connect to relay
3. earth, connect to earth

 The relay will have 4 pins marked, 30, 85, 86, 87
pin 30 is the live feed in to the relay, so a 10 amp fused feed from the battery or fusebox
pin 85 is the feed in from the switch, so connect this to the output side of the switch (no.2 above)
pin 86 is the earth for the relay, so connect to suitable earth
pin 87 is the feed to the foglamp, so connect to + side of foglamp

the foglamp will have 2 connections
a 12v+ , connect to relay pin 87
a 12v -,  conect to earth

mount the switch, relay and foglamp in suitable positions, wire it as above, turn on the headlight, hit the foglamp switch and hey presto! one illuminated switch and one fog lamp, thats the "proper" way to do it, but......
you could leave the relay out of the wiring circuit, and connect your switch directly to the foglamp, if your only having one lamp, this shouldnt be a problem except you may need to upgrade the dipped headlamp beam fuse, because you`ll be increasing the amps slightly (21w lamp / 12v = 1.75amps)

Thanks Tbone were not sure about if i need a relay but now i know big help thanks for info, will check with mot station if i need one. ::)

Just checked the MSVA manual again. Fog lamps & reversing lamps are listed as "optional", not compulsory.

No probs, but as Mr M says, it is not a requirement, purely optional. Personaly i wouldn`t bother, who needs the headache of extra wires n switches?

Prsonally I wouldn't mind having a foglamp on the trike - not that I often ride in fog but it can happen!

Got to agree with Tbone, if i dont need one wont bother with one, but thanks for all the info. ;D
