One of my front fog lamps has failed. Just days after getting its first MOT.
I am best getting an upgrade bulb(s) or just get a standard replacement?
It looks like a simple replacement job, as opposed to the main bulbs. One Discovery, gone

I vote for standard bulbs. The so-called upgrade bulbs (that are still legal) simply do not emit more light. They use a thinner filament which burns at a higher colour temperature, which makes people think they're brighter, but they're not, and meanwhile bulb life is reduced.

For example (Osram's figures):

There is only one halogen upgrade I would suggest (not applicable to the fogs), and that is the fitment of an HIR1 bulb in place of an HB3. Info on how here: http://store.candlepower.com/mohirbuba.html The HIR bulb produces more light, and legally, by using an infra red filter to reflect light back into the filament, heating it up and increasing efficacy. Luminous flux is circa 2300lm vs 1700lm for the HB3.

Thanks for your thoughts.
Will replace with like for like.
