Halogen Headlights and overheating switches

Alright,
A few months ago I replaced the sealed beams with Halogens on
the series III, all was going well untill the headlight switch
went up in smoke - at night on the way home from work, which was
a bit of a bugger. The following week the low beam on the stalk
packed in too. Now I have noticed the switch gets quite hot
after 10 minutes, something I never noticed with sealed beams.
Has anyone else had the same problems? I'am half tempted to put
a relay into the system but dont want to start making things
more complicated if I can avoid it.
Regards
Chris (Formally challisc - but can re-register?!?!)

I think its quite common
Ive heard it mentione allot on forums anyway, same with the s2
switch
I would get a relay in if your sticking with them

i run halogen on the switch without a relay and have had no
probs since fitting around a year ago, should i have them
running through a relay?

I've never had a problem too! Should I start getting worried?

As long as you are not using higher wattage bulbs then you
should be ok but, here's the point, are the switches new? Or
twenty years old?. The heat is caused by high resistance and
this will be years of dirt building up on the contacts as well
as the contacts wearing thin. Fitting new high quality switches
or cleaning the contacts will reduce the heat.
Fitting relays is a good idea as long as its done well. The
relays need to be near the load, ie the lights, the feed wiring
has to be up to carring the current and fitted with a fuse near
the supply and the most important thing is that all the joints
are soldered. After doing this you will see an improvement in
output from the lights.

Good Luck trying to find new High Quality switches for a series
III, I got two new ones - both gone up the duffer after a month.
Think a relay is in order, as mentioned it would be best located
near the headlights, plenty of room around the engine bay at
least.
To check just feel how hot the switch is after running the
lights for a while. It souldnt be too hot to touch, shouldnt be
overly warm ither!

Did you buy genuine ones or none generuine ones ???
I have used this guy

/>
for a couple (on different vehicles ) and had no problems
....they are 24v mili spec ones so require the plugs modifying
BUT for genuine ones they arn't badly priced .
Needless to say he isn't advertising any ATM that i can see BUT
might be worth an ask ???

I got non genuine as I couldnt sorce good ones, I knew I was
taking a gamble - but a tip to all AVIOD! A genuine one is
currentlly fitted but as I say - rather hot for comfort.

Might be worth checking earths ....as if you have a poor earth
(as if on a series lol ;D ) A bad earth may cause you to pull
high amps

I fitted Halogens to my 1st S3 and had no problems, but relay
may be wise with old wiring n that.
I did have a NEW Lucas stalk self destruct recently with my
sealed unit high beam :-\
