lykag6 Member 29 Member For: 3y 9m 21d Posted 08/12/21 03:24 PM Share Posted 08/12/21 03:24 PM Hey guys, Earlier this year when I bought my car not long after one of my front headlights went out and the other looked like it was weak as piss so I got them both replaced (the standard one, not any special brand - forgot the name but you know what I mean). Tonight, after maybe driving 5000kms since then, I realised one of my headlights is completely dead again. How is that possible? Can confirm I definitely haven't left them on overnight or anything like that to overuse it etc. With lockdowns too, it's barely done any miles since putting two new globes in.

It's piss easy and need not be done by a mechanic. Link to comment Share on other sites More sharing options...

Posted 09/12/21 06:30 AM Share Posted 09/12/21 06:30 AM (edited) Do you happen to get the headlight fault error pop up a few times a month? Or do both the low and high beams fail for the globe or just the low beams? For two years I chased an issue whereby I would get headlight fault errors when turning the car off - it would only occur randomly about 2 -3 times a month - and roughly every three months the low beams would fail, sometimes both globes, sometimes just the one. Once it was fine for 6 months. I replaced the globes with Nava and Phillips crystal visions multiple times and neither resolved the issue. Then one day I thought stuff this and replaced them with the cheap on sale Calibre brand from Supercheap and they - touch wood - have not failed in nearly 2 years. The only thing I did was change the globes, the battery is an Optima yellow top - installed by the auto electrician when my battery was moved to the boot - and has been fine each time it's been tested and only the low beam elements failed. It was really doing my head in, hence why I went the cheap brand, because if I had to keep replacing them, stuff spending $100 or more a pop doing so. Also each time I replaced them, I always wore gloves because of the reason given by K31th.

Both are totally fine in the FG mk2 as they have "projector" style headlights which focus the light fine for either aftermarket replacement.

Posted 09/12/21 07:48 AM Share Posted 09/12/21 07:48 AM I bought the LED upgrade kit from Superior vision a month back but am yet to fit it as one of the headlights has something caked onto it, so I'm just going to hit both of them with one of those restoration kits first. https://superiorvisionaustralia.com/product/fordfalcon/ – 2x LED High Beam Bulbs – 2x LED Low Beam Bulbs – 2x LED Fog Lights Bulbs – 2x LED Parker Bulbs – 2x LED License Plate Bulbs – 2x LED Reverse Bulbs So I'm going to fit that over the Christmas break Link to comment Share on other sites More sharing options...
