Assuming one did not wire the euro city lights to work with the side markers, what is their normal operation with a bulb installed? What switch position?

MikeTangas - did it require a special 5W bulb?

Just installed my euros Thursday and echo the sentiments of everyone else on the forum - truly amazing. Thanks.
