Right, lets try and put this to bed......
1st - check under the bonnet (thats the big black thing you can see over the steering wheel ) and see if by any chance you have these two relay boxes bolted to the wing (the dotted lines)
If these are present then you do indeed have 'daytime running lamps' ie the headlamps will automatically come on with the igniton....... something I have never seen before
if not..... the relay switches are in the covered fuse box in the engine bay, just above the battery, it has a handy map on the cover so you will know which relay / fuse does what.... take the cover off (2 press in clips either side) - you will notice that many of the relays ARE THE SAME - they just pull out vertically with a bit of force - swap with another non vital one (suggest central locking) and test it with that
I have just had a look at my cars, my facelift has MB629085 for several relays - my dead pre facelift has MR588567 as the part number but they appear to be the same - well I just swapped them and didn't blow up anyway.......
You say both the front and rear lights come on with the ignition?? if so it is unlikley to be relay related as they are switched by 2 relays?????

Not all the relays are the same, but there should be 4 or 5 the same.... the ones nearest to the headlamp relay are (from memory) for the central locking and aircon and on both my cars are the same relay.... bear in mind that I have a different car to you so if yours is any different explain how (pictures are good!) and we will see if we can work through the problem.....Originally Posted by gtz101
.... will the lights work if you replace the relay?.... well, finding out is kind of the point of the exercise, is it not??
Did you check for the two boxes on the drivers side wing - like the first diagram ?????????
I didn't see any double black boxes anywhere.
I have managed to take some quick pictures (see below - you might need to double click to zoom in for detail). I was wondering if someone could point out with arrows which one is for the headlight (high/low beam). please
I don't have a replacement so I suppose I will need to pull an existing one out from there so again if somebody could advise which one would be best to pull out and test. I know Nutter John said earlier try central locking one, which one is that and will it mess up C/L ?
relays are letters, fuses are numbers - relay for headlights is 'E' - would suggest exchanging it for any relay that has the same part number and is 'none vital' for example 'G' which controls the horn - as long as it is the same part number (it is in my car)
this will test to see if the relay is at fault for the lights comming on
Can you confirm if the rear lights come on when you turn ignition as well as the fronts?? - 'cause if they do it is unlikley to be relay related
only the rear brake lights show up with Ignition on.
Ok so Letter E from the diagram controls high/low beam?
What about those that have both letters and numbers? E.g. theres about 6 relays with MB629085 written on it in my fuse box.

'E' is headlights, 'D' is main beam i think
Right, following a request from GTZ i've looked under the bonnet and the piture below should clarify everything ( I hope!)
All 7 relays circled in red are the same, looking at the fusebox cover it looks like the two we're most interested in are 'D' and 'E'?
Details on the relays:-
Relay
MB629085
156700-0780
12v
Denso
Hope this helps
BTW My car is a 2000 post facelift v6sport with the same bumper lights etc as GTZ101
No longer empty and frantic...
Perfect!
I will work on it tommorrow afternoon and I will provide feedback on here in the evening.
Thanks for the input guys
I will put in the horn relay and carry out the tests.
I know this post is years old, but i now have the same problem and this didn't appear to be solved!
Ive had my Legnum VR4, 1997 pre-facelift R reg, nearly 6 months now, an amazing car and loved to bits but noticed the other night the headlights turned on by themselves while i was driving, not on the stalk just on the dash! It was starting to get dark when this happened. Full headlights not sidelights. When i stopped i checked the back lights and they were on as well, indicator stalk still saying set to 0. Since then its only turned them off at night when the engines stopped, refuses to otherwise! This however only happens at night, i get to decide if the headlights should be on or not during the day! Its not a problem as its just as night, but its really just because i cant believe i didn't notice this before! So can it be light sensitive lights or is my car been next to my 5 turbo to long and picking up bad habits??! Thanks for any theory's in advance

Owned by a Renault 5 Gt turbo & the new addition Legnum Vr4!!

Sounds like something a bit screwy is going on. The cars arent fitted with day running lights, from what you describe it sounds like you car has auto light switching. Never heard of it before.
They deffo dont come on in daylight by themselves?
I don't use the car every day, but its not done it during the day so far now ive been eagle eyed! Used it last night in the dark and lights working by themselves and im just back from the dentists this morning and it let me decide Like you say i think its messing with my head, i shall go out once dark and test again! Im just a wee bit worried it is a wiring problem or something and more things will begin to happen!
have you got odd looking thing on the dash pointing out the front screen.
if so it could be an after market auto light on system. take a pic of dash to let us see as you probably don't have anything to compare it with to see if tit looks normal.
Bye for Now!
Seeing as it's a VR-4 (IE it's come in from Japland) there's a good chance as Dave says that there's an auto lighting system on the car somewhere.
Thanks, just went out and took photos of dash........erm problem solved theres a little round box in the corner that if you look really closely says 'auto light' cant believe its taken me 6 months to notice my car had this! Im quite particular with my lights at night though, and usually stay in the car till the turbo timers off so thats why ive not noticed before Thanks for the help everyone
Theres another thing on the other side though, is this something to do with the jap GPS?
Thanks again,
Sharon
Derek (SGHOM) had a very similar system on his 1st VR4.
Yes, the square box is a GPS reciever. Has your car got the MMCS, or an aftermarket thing?
Thanks My cars Jap owner had a thing for Alpine i think, every things Alpine, its got double head unit and Alpine Jap Sat nav box (don't think there is a disk in it) under the chair with a free standing tv screen (that does nothing but show dots lol) From what ive read i don't think i have this MMCS.
Yeah, you deffo don't have MMCS. The MMCS uses a similar GPS antenna but it's mounted 'in' the dash - I did wonder if a previous owner had moved it but seeing as you've an aftermarket system that's now a redundant question!
i see you have the ralliart dash..good stuff
