Absolutely no modifications to switches, wiring, etc. This bulb is integrated with the logic to switch between constant/flashing mode by simply cycling the light switch. 【ENHANCED SAFETY】On anchor or a mooring at night, each vessel in the water, relies on a single anchor light bulb to identify itself whether a john boat or a cabin cruiser. Anyone who has operated a vessel on anchor at night has experienced the anxiety wondering if an approaching vessel has seen your anchor light. What if your anchor light could convert to a flashing light to enhance your visibility?? WITH THIS BULB YOU CAN! If an eminent collision is perceived while on anchor, at a moments notice, the vessel operator can cycle the Anchor/Stern light switch to activate Flashing Mode and significantly increase the probability of being seen which could ultimately prevent collisions.
