Newty, these Abyss lites are $220 each. I put two back there. They have other ones that cost a bit more. If you want to see them all just go to Abysslite.com and the prices are on the site. Now the cost of having someone else put them in for you is another thing. Labor cost is where you will have to pay the most. I didn't want to have to use my off time working on my boat. I want to play in it so I had the guys at Earmark Marine in Lewisville, Texas put them in. They did all my LED work ... other then the dash lights. I did those myself.
