What do you say? These are yellow "signal lights" that turn on and off automatically, day and night, as they should. Do yellow lights really drive away more bugs? I have no idea! But I've always used them on deck during the warmer months and I suspect they're a little better than most white lights in that regard. Both arrived undamaged and have worked flawlessly for the past few months or two summers until I recently replaced them with white (winter) headlights. Note. These indicators appear white until they light up. How do they resemble a typical light yellow beetle. flow of light? It might look like a 40 watt incandescent bulb - give or take a little.
