My fog lamps quit working in my 2002 Regal. Before I take it to the dealer,
I wanted to try changing the bulbs in case by some fluke they are just both
burned out. According to a bulb website, it's a #893 replacement bulb. On
the bulb replacement page of my owners manual, it does not list the fog lamp
bulb along with the others, instead it says "see your Buick dealer". Is
there something special I need to know to change the bulbs?
Also I notice there are a million websites that sell the whole replacement
fog lamp (minus the bulb). I'm curious why they would be so commonly
replaced - isn't it just another fixture, like a headlamp assembly? Or is
there something electrical in them that goes bad?
Wouldn't be terribly unusual; halogen low-voltage bulbs operated on a
common electrical system tend to have extremely similar lifespans (dying
within hours or days of each other is not at all uncommon). This is
especially true if you use your fog lamps a lot -- i.e., if you live in an
area with a lot of fog and have reason to use them frequently, or if
you're one of these who insist on driving with your fog lamps on all the
time, even when there's not a hint of fog within 50 miles.
Which "bulb website" told you that? Master US bulb application data has it
as an H3 -- not the same at all as an 893. Master application data is
occasionally incorrect, but there's a ton of garbage bulb info out there,
so it matters which "bulb website" you were looking at. Hope you weren't
tempted to buy any of this ultrablue/superwhite/silverbright/etc. type
Tends to lend support to the H3 theory -- GM continues to pretend bulbs
that have been common throughout the world since 1965 (like the H3) are
very special, rare and hard to find items.
Because they are mounted down low where rocks tend to take 'em out.
