These are lights I use on my trailers and truck beds, but you can use them anywhere you want to be seen! They put out a very intense, "crisp" light that looks good and is very visible, even in the day time. At night they are very "noticeable"
They have a 10 year life (100,000 hour!) and carry a ONE YEAR warranty! No more bulbs that burn out at the worst time (and you always put off replacing) LED's are rated for 100,000 hours compared to 3,000 hours for incandescent bulbs. Consider real world circumstances where more incandescent bulbs need to be replaced within one year. An LED light will last over 20 years before needing a replacement.
Also, remember that LED bulbs use very little current, so you can install as many of these as you want and not worry about a system overload (only 50 milliamps, or 1/20th of one amp!) LED's are very energy efficient and consume less up to 90% less power than incandescent bulbs. This reduces the load on your electrical system including your battery, alternator, and power converter resulting in direct money-saving benefits.
These are surface mount, requiring no hole to mount "into". They provide a easy method to install quality LED lights on any surface. The lens used on these LED's allow them to be seen from many angles, not just directly in front. Actual size is 2.60" L x 1.90" W x .66" D and mount with two screws or adhesive or double sided foam tape.
