[s-cars] HEADLIGHT UPGRADE

[Vincent Fregeac]

In fact, high wattage 900X bulbs are fairly common, but not in auto
parts shop but you can easily find 900X bulbs up to 130W for
snowmobiles! There are a few points you should take care of when
choosing higher wattage bulb:
- First, the bulbs MUST be relayed. Stock bulbs can already fry the weak
Audi switches so higher wattage bulbs will definitely fry them.
- Second, the heat exchange and the temperature resistance of the
headlight are limited, especially with the projector design of our
headlights.
- Third, the temperature resistance of the bulb sockets is also limited
so even with for the high beam with a larger reflector; 130W bulbs may
not be recommended. The European Audi headlight design usually have
metallic sockets and can take more powerful bulbs but I've not BTDT with
the urS.

The only experience I have with DOT headlight is with the 90 Quattro,
both 20V and 12V. The crappy DOT headlights these cars have can handle
85/100W relayed with no melt sockets or fading reflector. With the
smaller enclosure for the urS high beam and the projector type low beam,
I cannot guarantee these wattages can be used on the urS though. Yours
to try.

Xenon charged bulbs are a waste of money despite what the advertising BS
says about "super white burn-out-your-retinas light, looks Ricer blue in
the
housings". Installing higher wattage bulbs will eventually cause the
stock
headlight and/or dimmer switch to fail, but this isn't much of an issue
with
stock lights since high wattage 900x bulbs aren't that common. High
wattage
bulbs have to be relayed as the OEM Audi switches and wiring are
marginal.

You've got two routes for effective headlight upgrades:

1. An aftermaket HID retrofit for the 900x low beam on the stock lights
(around $500) which will improve low beam performance but leave the high
beams marginal.

2. Upgrade to Euro lights (~$700 - $900) which use the H1 bulbs for high
and
low beam. The low beams are slightly better with 55w H1 bulbs (heat from
high wattage bulbs here can damage the reflective coating on the plastic
low
beam projector bodies) but relayed 100w bulbs in the high beams result
in
superb distance vision. The low beams can be upgraded with a H1 HID
retrofit
(~$500).

Dear Listeners:  I am considering a headlight upgrade for my 95.5 S6,
and
have read the information http://www.urs4.com/technical/headlights.html.
I
realize that ultimately this is the BEST way to go; however, due to
limited
$$$, and too many upgrades pending, I am considering just replacing my
stock
bulbs with Xenon bulbs, which are available at
http://www.eurolights.com/.
I have read that by just upgrading the Bulbs without upgrading the other
electrical components my damage both the lenses and the other components
overtime.  However, this company claims that their Bulbs will not harm
the
system http://www.eurolights.com/, and they state that no other upgrades
are
necessary.  Your thoughts appreciated.  Thank you.

Dan
95.5 S6
