Headlight element keeps blowing on low beam

[Mattel]

On my corolla alltrac one of my headlights (Drivers side in the US) keeps blowing lowbeam elements. High beam is fine and the other headlight is working perfectly.

Perhaps it is an earthing problem or the globe connector? Anyone have an issue like this before?

that's weird. the fuse should always blow before anything else in the system. is the headlight fuse the correct rating?

make sure the head light mount is secure so it will not vibrate. When the element is energized, vibrations can cause it to fail early. Also, some brands of bulbs have more support for the element than others, if you drive rough roads, these more durable elements will hold up better.

Also, check all your connections, an intermittent connection will also cause it to fail by thermal fatigue (thermal cycling).

This is all true bad connection and wiring can cause the biggest problem later

Thanks all! you are a wealth of knowledge!
DLB! I remember looking at my fuses in the kick panel a couple of months ago and I remembering wondering if the small diagram on the hatch to the fuse box is mirrored or a copy of the layout of the different amp fuses?

It is not a mirror image

thanks Ridlbox. I checked the fuses and I had a few of them in the wrong spot. but the headlight fuses are under the bonnet and were correct. I think what I might have done is handled the glass of the halogen bulb as I forgot that its best not to touch them. Have replaced now with the last of my junkyard globes and all seems good. Thanks for the help guys!
