Why not full power?

In the US, the DRL's seemed to be a last minute change. The IP lights
were run at full power instead of 1/2 power like on later models. This
weaked the bulb sockets, causing them to loosen and lose electrical
contact. Sometimes bending the contacts in the sockets restored
contact, at least for awhile.
There was a service bulletin that specified installing a 'ballast'
resistor to drop the voltage while the DRL's were operating. I think
this was fixed in the late '95 or early '96 models.
In any case, you really don't want them on full bright anyway in most
cases. Messes up your night vision. I run mine just enough to see the
gages. Never had to replace a bulb or tweak a socket.

When running those illumination bulbs at full power they run hotter and are
more likely to melt the plastic around them. Then they may lose their
electrical contact = no light. 8^)
I think I retained this info from one of Lost In Space's posts and am just
spreading the word. ;-)

yep, that's it. The replacement switch unless changed no longer turns the
dash/parking lights on when in DRL mode. But then again if your bulbs only
lasted about 13 years... don't worry, be happy.. and just replace the bulbs.
