(2) Any motor vehicle may be equipped with not more than one running board courtesy lamp on each side thereof which shall emit a white or amber light without glare.

316.2397 Certain lights prohibited; exceptions.--

<<Insert stuff about Police/Fire/Road Crews here>>
(7) Flashing lights are prohibited on vehicles except as a means of indicating a right or left turn, to change lanes, or to indicate that the vehicle is lawfully stopped or disabled upon the highway or except that the lamps authorized in subsections (1), (2), (3), (4), and (9) and s. 316.235(5) are permitted to flash.
No mention is made specifically to DRLs, but the White/Amber requirement for Front Lamps would seem to apply. -- I'm not a lawyer; the judge's interpretation may be different !! --
