This car eats headlights.  For those of you not familiar, this car has a 4 bulb system.  It burns out probably 3-4 low-beams in a year.

This ain't cheap at $25/pop for these 4351 sealed beam units.

Can anyone recommend a cheaper, possibly higher performance conversion option?

Thanks in advance,
Josh

P.S.: I've heard sparse recommendations (from parts counter staff) for dielectric grease on the terminals.  Thoughts?

There are conversions available, how good they are I don't know.  Might
want to check with Daniel Stern.  Stay away from "blue bulb" crap.

Dielectric grease is a good idea, but it won't make the bulbs last any
longer, they will just keep the connectors from corroding.

good luck,

you probley have either high voltage at the lights or low. you need to
check it as the fix is different depending on which it is. KB

Have you checked the generator's output? Sounds like it's pushing too much
voltage down the wires.  Check the voltage at the headlight plugs and with
the headlights in the circuit. Headlights on, engine on. What voltage are
you getting at the plugs?  More than 14 is bad, and may indicate a bad
generator or regulator within it.

Could also be a bad ground.

My headlights down burn out as fast as yours (1995 Camaro), but I do
seem to replace them more than other vehicles I've had.  At $20+ a
pop, you do tend to notice the replacement cycle :)

For more hits, use "camaro headlight conversion" (without quotes) at
google.

How are they blowing out?  You see black stuff on the inside of the bulb
or not?

>P.S.: I've heard sparse recommendations (from parts counter staff) for dielectric grease on the terminals.  Thoughts?

You should definitely use it.  It will greatly prolong the life of the
connectors.  I doubt it will fix your problem at all, but twenty years
down the road you'll be glad you did.

I have a '97 Camaro and I've never had a bulb burn out. Of course, with
the turn signal DRLs I probably use them far less than you, but they
should still last several years with normal use. I suspect the voltage
to your headlights is too high, or there are voltage spikes. Measure the
voltage at the battery, more than 14.5 is too much. Do you have the same
problem with the fog lights?

Here's one headlight upgrade which supposedly gives a substantial
increase in seeing distance, and with replaceable bulbs too:

That certainly looks better than what my web search turned up, which
appeared to be stock sealed beams modified for replaceable bulbs.  I'd
be tempted to try the ones you posted, Hella generally makes a quality
product.

here are the actual headlamps used for that project:

Are you thinking of replacing that old high maintenance 944 with a more
durable and faster Camaro? I thought you already had e-codes on all your
vehicles...

Yup, I first saw that page a few years ago following a link from
Daniel's page IIRC. Personally, I'm happy with the light from my stock
low beams, and with the aid of a pair of driving lights the high beams
are the best of all my vehicles.

Nope, not at all... and yes, not counting the F-150 (for which they are
sadly unavailable.)  Was just still thinking about the OP's situtation...

I seriously doubt I could find a Camaro for a price I could afford,
which is NOT true of a 944.  Of course, I have to admit to being partial
to the first two generations of Camaro for styling reasons...

Yeah, I know, just teasing you a little...

While I don't know the market price of a decent 944, I'm not surprised.
Old cars that are expensive to maintain tend to be cheap, and "everyone"
would rather have a 911 anyway. Still, it's probably better than a Sirocco.

Funny you should mention that... I loved my old Scirocco and am still
kicking myself for selling it.  I'd buy it back in a second if I knew
where it was today, and I haven't seen a decent one on the market at
all in quite some time.  Every now and then I'll even search eBay for
one and come up dry.  If I could find a rust free round-headlight
roccet, I'd buy it, no matter how ragged the mechanicals were.

But for reference, you could probably pick up a decent, running 944
(naturally aspirated) from anywhere from $2-4K depending on location.
$10K will probably get you a near-show condition Turbo.  $15K should
get you a modified Turbo that will eat 'vettes for lunch.

Sure, "everyone" would rather have a 911, but for a driver, a '44 is
probably more practical.  It's actually a better handling car than a
911 (heresy!) and doesn't have near the lift-throttle oversteer issues
which can be fun for an experienced driver on a track, but scary if
you're just trying to get to work in a snowstorm.

You need to think outside the box. Here's what you do; Buy the cheapest
Scirocco you can find on eBay or whatever, complete with all paperwork,
and then buy an other one in mint condition from Germany. Transfer the
VIN and the US-spec parts you like and you'll have a US "legal" Scirocco
in great condition without spending an arm and a leg. Of course, you
should have done this a few years ago when the dollar was worth twice as
much.

No thanks, I'm about to buy an apartment for over $100,000 so I need to
keep my expenses under control. Besides, four cars and a motorcycle is
more than enough...

Well, you do have the weight on the drive wheels, and I like
powerslides. :-)

Last time I looked, there weren't any US-spec ones for sale, period :(

The point is that you buy a Euro-spec one in Europe, and equip it with
US-spec parts from your "parts car." Voila, you have a mint condition
US-spec Scirocco...

I don't have *any* Scirocco in any condition, is the problem with that
plan...  do a search on eBay Motors for "scirocco" and you'll see the
issue.

Where did they all go?  They surely ALL weren't either scrapped or
sold to collectors...?  I mean, they were made from 1974 to 1988
(later in Europe) so you'd think one or two would pop up for sale
occasionally.

Also, the authorities may take a dim view of your plan...  to some
people what you suggest would be similar to taking, say, a 318
Barracuda and a clapped out Hemi and doing a Vulcan car meld, and
apparently that is a big no-no.

The rotted out 'really' fast around here.  I remember friends freaked
about it, nothing left for a subframe to bolt to....  Haven't seen one
in years.

That is odd, mine held up really well, and so did my '84 GTI.  I
wonder when VW started using paraffin undercoating, that stuff is
great.

_________________________________________________

Excess heat shortens bulb life.

1.)  Make sure the connections are not corroded and that
the wires are not partiallly broken, generating excess heat.

2.)  Consider using a fatter wire or a ground strap on the
bulb socket to carry away excess heat.

3.)  Provide clearance around the socket & connector to
allow air cooling for excess heat.

4.)  Use thermal dielectric grease in the connectors to help
conduct into the wiring the excess heat.

Good luck.

My 96 Z28SS (bought new) has never burned out a headlight.  I suspect
you have one of the problems listed above or perhaps an overvoltage
problem.

You need a new voltage regulator.  The too-high voltage on your electrical
system will eat any bulbs you get unless, of course, you find some 17V
bulbs.
On most cars since '75 or so, the voltage regulator is internal to the
alternator.  Some overly computerized cars control it in the ECU, but
I doubt any camero ever did that.
If you pull the alternator and bring it into an auto-electric shop, they
can replace the voltage regulator and save you the cost of a whole new
alternator.
