Just a Heads-up, I stumbled across a very cheap source of LEDs. Go to the Walmart website and search for LED auto bulbs, a very large selection will pop up; you can put your order in through Walmart and it is transferred to a company called Tasharina which ships direct to you with no tax or shipping. I have replaced almost all the incandescent festoon type bulbs in my 280 with LEDs, (some red) for an avg cost of about $2.00/bulb. I used the 41mm festoon base for all of them; the 39mm probably do OK in the cabin but the bow & stern lights need the 41's. I used the ones with the flat plate and the little diodes all facing one direction, figured they would throw all the light out towards the lens, but there is a large selection to choose from. I still have to get up the mast for the anchor light and the best I could figure is that is a 31mm and I got the type with the diodes mounted 360 degrees, but not been up the mast yet.
