The standard amber turn signal bulbs reflect a little bit
too much orange color to the inside of the headlights so
they make the headlight look orange. I replaced mine with
silver-colored bulbs. These are readily available in
automotive parts stores and can be found on the internet as
well. The bulbs have a silver coating on the outside but
will give off a normal orange color when lit. These are the
Philips Silver Vision I used.
