One option for LED (what I did)
Go here M4 Products
and look at the first three bulbs. My trailer is new so I used the wedge base bulbs. You may use one of the others. They have Soft white (yellowish) and cool white (white light). We chose the white ones and are very pleased with the increase in light over the originals. You may want the white ones in the range hood and over the dinner table but some soft whites else where. I'm using these Economy Wedge Based RV Retrofit LED Light
everywhere including the porch.
