What is the best solution to make your vehicle more visible when visibility is poor, such as at dawn or dusk?

At dawn, dusk, in rain, or snow, you need to make yourself easier to see. If you are having trouble seeing other vehicles, other drivers will have trouble seeing you. Turn on your lights, use the headlights, not just the identification or clearance lights. Use the low beams: high beams can bother people in the daytime as well as at night.
