Somewhat off topic, somewhat on topic rambling...
For what it is worth, in my quest to make all my cars European legal... {amber rear turn signals which the Insight already had even though I have no intention of ever taking them to Europe} ... I learned all vehicles operated in the United States made after a year I do not recall are required by law to have front and rear side markers. With that said, they do not have to be lit, a reflector is good enough as they are not required to function as a turn signal too.
But each manufacturer is different and even different trims of cars have different set ups of side markers. My Challenger's front side markers are wired directly to the headlights, while the rear are reflectors. Some trims/options have lit rears, some have a separate circuit for the whole system. My Silverado, that is a bit more complicated, they are tied into the headlights and the hazards, but not the turn signal.
Anyhow, back to the point... tape and a Dremel tool make a nice, clean cut. Start too small, sand to finish. A lot of stand alone side markers just snap into place. The wheel well covers come off very easy so you can get to the back. I would roam around a junk yard and find some side markers you like because the biggest problem you will find if there is not some sort of kit... finding the plugs to hook them up. As recent events have taught me, getting to the headlights is a scientific impossibility without severe disassembly of your front end {exaggerating, slightly}. If you go that far, you are more than welcome to sign up for
Honda's Site and send me the wiring prints. I could design a circuit for you that turns them on and off for whatever set up you like without leaching power, dimming your other lights. I give you my utmost assurance that your car will probably, maybe not catch on fire after that.
