uprated headlamps - a warning

Dec 23, 2005 30 Replies

Just spent an hour or so fixing a friend's car.



someone previously had fitted 100/55W bulbs, as I found out when investigating why the headlights had completely died, which is of course not funny when driving in the dark. At least they didn't do what mine did on the 110, and go out when approaching a corner.



switchwork overheated, melted the connector. Had to replace the connector for the dipswitch and the switch unit, and of course fit proper-sized bulbs.


Thanks Austin. As I've said before, the LR's appear to be the only vehicles that cannot cope with off-road bulbs.....

Which is why mine now has a set of relays with their own feed which use the original headlamp wiring for the relay coil.

I'd actually recommend doing this as a matter of course - the light output even with standard bulbs is quite a bit improved with this setup - the resistance in the standard wiring must be phenomenal

P.

Its what destroyed the panel loom on our ambi too.

I dont think i'd even entertain the thought of running anything more than standard bulbs on the 101 original wiring.

I was going to rewire mine and fit new normal wattage halogens. as it is its got the orignals in and I dont think theyre even getting the full 12v as they are like candles!

this was a monetgo. The *wiring* is massive fat stuff, but the switch and/or connectors don't seem to have liked it.

pity he didn't read alt fan landrover headlight posts before he fitted them then.It seems to come up about once a month, lucky really that the loom didn't catch fire as well

Also illegal too. Better to fit some decent 'quality' lamps, no hike in wattage, just a better spectrum of light. The Xenon +40% (same wattage) i fitted to the RRC have made a nice difference. I made sure (after all the hullabaloo on here) that they didn't blind anyone

Tom Woods uttered summat worrerz funny about:

If I understand the operators manual correctly then the wiring was installed prior to any consideration for Eberspacher heaters. Therefore it's supposed to get hot, tis the only thing that did in the GS's then they bunged the Ambi bodies on and forgot to remove the electrical central heating.

That'll learn you to fit over-power headlamps without upgrading the wiring and switchgear to cope. You're lucky it didn't catch fire.

Nah read the post... Austin's mates motor. Hence Austin very lucky.

Is the collective noun for a group of relays really a herd?

It wasn't, I hasten to add, me guvnor. It WAS the reason Wendy only cost me 2 grand, so I can't really complain. Bob has relays on his headlights, courtesy of Mike Derrick, occasionally of this parish. Did a very neat job too.

When I rewire Wendy (oh, come the day), She'll be all relays.

difference. I made sure

I know that, and so does the owner, and so does the previous owner. Chances are the bulbs were fitted before that. Do you check what bulbs are in the headlamps when you buy a motor, if they're working well?

OK, I do, 'co I tend to have the expensive kind fitted at want to put 'em on the new one, or more validly, not sell 'em with the old one.

but apart from that, I wouldn't check 'em unless there was a problem.

RAC bloke crosswired the sidelights to the dipped beam, and uprated the relevant fuse, as a "get-you-home" fix. Not entirely sure that was legit, really. The sidelight circuit and switchgear is designed to take 4 sidelights (or maybe 6 if it has double rear bulbs) and a passel of panel lights, for a total of about 50 watts - adding another 100W to it is rather a serious overload. The journey home was quite a distance, I gather. Wonder if the RAC would have admitted liability if it went on fire...

read the post properly, yerbugger.

on the 110, I didn't have over-powered bulbs. The switch just died. it's possible it had been abused in the past though.

I tellyer one thing - having the lights all go out in the dark is a good one for testing whether you were really looking where you were going... If so, you have a mental picture of enough of the road ahead to stop without going off it.

Surely it's a 'click' a 'clunk' would be contactors!

No, would you hell as like matey! With any of LR meagre early headlamp offerings it would be, of course, obvious had you driven by glow worm light before!!!
