I have since tried a new 110w globe like the normal ones Shiny and me have used for ages, BUT alas the left hand low beam lasted about a minute then DIED.... Wot thuh
So does anyone out there in ST land know of a fix for this problem??? :think1
Thanks in advance :blu13left :thumbs

During the brief time when the LH low beam is working, does it look the same as the RH? Like is it brighter, indicating it’s somehow getting a higher voltage (unlikely unless you incorrectly installed that nuclear plant under the seat), or does it flicker?
I’m putting my money on an intermittent joint. Filament-based bulbs draw a large inrush current on start, typically 10X their running current, which is a massive caffeine hit to the filament. Too much of that in a short time will kill them.

In reply no:3 I copied the wiring diag from the manual which shows that the LH headlight is controlled by relays whereas the RH headlight is directly controlled by the switch.
Maybe that will help in identifying the problem.

This can be caused by oxidizing of the terminals, loose fitting terminals, or the terminal has come loose on the wiring.
The high resistance causes higher heat in the lead and the bulb, and this raises the overall temperature of the bulb too higher than normal, which can cause failure.
So also check if the new bulb is slightly dimmer than the right. That is a symptom of a high resistance joint.

As bizarre as it sounds, it could also be a high resistance joint in the headlight lead at the terminal.

Good point Gary. Last week we lost power to our house, and the Energex guys found exactly that scenario. The 30 year old fuse block out at the post had developed a high resistance connection and had overheated to the point where it destroyed both the block and the fuse.

Sometimes it appeared that the globe had blown but filaments looked ok - put the globe back in and it would work. That happened a few times and eventually the plug just fell apart in my hand. To much heat so I replaced the plug with a new ceramic one and it's been okay since.

Because copper is a soft metal, it will 'migrate away' or ooze away from a point where it is under pressure.
We've had a similar thing with a house switchboard where a light circuit became intermittent and the circuit breaker would trip.
We also had a Power Point in the lounge room melt on the active wire, when using a fan heater. Again due to a high resistance joint in the back of the Power Point.

What happens is the tail and brake lights dimly flash when the indicator flashes.
The electricity was finding an earth trough the brake and tail lights circuits.

I've also seen a common fault in series 3 Land Rovers where a high resistance joint in the earth joint at the rear of the vehicles caused a weird symptom.

I've seen that on other vehicles occasionally (trailers are good at it) and figured it was a short of some kind but hadn't heard of high resistance joints.

The next thing to check is the headlight switch as the switch supplies power to left headlight and relay. The relay then supplies the right headlight and high beam indicator on dash.According to my manual and my experience, its the other way around. Switch controls the RH side and the relay the LH.

Option 1 oder mini headlight loom from USA $300.00+$150.00 shipping
Option 2 see pic 1
Obviously you know which option was chosen
"2"As you can see lots of thought went into this operation.
Check the old block and leave a comment if you want

I think I might have been correct. That's a surprise.
As is the level of melting in the connector. WOW:
These areas circle in red are giveaway signs of a high resistance joint.

Wow, now that was one shagged bulb holder, no wonder it kept blowing.

See mine here; globe never failed but kept going out. Moment I touched the plug the light would come back on until one time the plug fell apart. Replaced with a ceramic plug
