Anything flashy. Try a mepps or my choice panther martin.

Many times small glass minnows will ball up under the light and will either stay out of reach or be too small for use. Thus, it is advisable to bring cocahoe minnows along. Nevertheless, don't neglect using the 3-inch long glass minnows that often show up. Trout love these type minnows and will strike them even when in a finicky mood. Likewise with other types of bait that will show up, like ballyhoo or needlefish. That's right, needlefish and ballyhoo! Specks will hammer these species no matter how long or large. I've caught specks on 2-foot long needlefish. But as with all baits, they have to be properly rigged and presented!!!
