No Low Beam Lights - Resolved!

[StormyKnight Advanced Member Find all posts View Profile Close StormyKnight]

The car has been left in town & I will be checking it out in the morning so I haven't yet had a chance to check anything as of yet.

Parkers work
Low Beam Doesn't
High Beam Does
Driving Light Don't (But I suspect they somehow rely on the low beam working....not sure how since they should only activate via the high Beam - they are IPF with the button control thingy in the cabin)

My check list will be....

Fuses (Looking at the circuit diagram there is a seperate fuse for left & right so this is unlikely to th eproblem since both are out)
Relay (One common point is the Headlight Relay, but I think both low beam & high beam get thier +12V form the same point)
Combo Switch (Makes the earth connection for each mode, i.e. high, low, parkers - looks like the only thing that makes sense if that is not swicthing for low beam.)

......is there anything else?

The reason I say Relay is I have read several reports of the contacts arcing, we also run the lights almost always during the day since our Prado is "Invisble Silver" in colour! & it makes the dash easier to read....

Cheers

Re: No Low Beam Lights

A long shot of course, but maybe, just maybe - the low-beam filaments have failed simultaneously. Only really had this happen once in 25 years of driving.

Reminds me that I really should get back home:-)

Re: No Low Beam Lights

Well I'm a little embarrassed... ops:

Here I was thinking it was the worst possible outcome & whilst a little tricky reminds of the old saying KISS (Kept it simple stupid!)


The right lowbeam had blown, the left was partially blown....it would work if I tapped the globe on the fender whilst I had it out of the headlamp assembly...

However the odd thng was the high beam indicator light didn't turn on either, even though the high beams where on. I think that it relys on an earth path back through the low beam globes...

Anyway I have better understanding of how the lamps are turned on.....

Thanks Keepleft for replying....

Cheers

What causes both globes to fail at the same time what was that the fault? I just got off a 3 hour train ride in the pissing rain turned the head lights on both low beams stopped working just looking for ideas at where to look tomorrow if I get a chance? not much info on prados on the net compared to most other cars even the wiring diagrams I brought off the net are nothing like my prado in the few cases I've looked hard at them

it was both low beam elements blown ? At the same time for both globes to go something must be wrong ? yeah the high beam indicator on the dash must run thru the low beam globes some how as it wasn't working either?
