If you do a lot of boondocking (no hookups while camping), then you know battery life is one of the most leading things you must plan for, especially if you have a small battery bank. One great way to save a lot of power is to change your existing incandescent lighting to Led lighting. Led stands for light emitting diode and provides light in a very different way than incandescent or fluorescent lighting sources. The biggest advantage for a boondocker is that Leds wish very puny power to operate, so you won't have to be so conscious of switching off lights when you don't need them.
Just how much power can you save by going Led? In a typical voyage trailer of say 27 feet with a super slide and a couple of bunk beds, you may have upwards of 20+ 12 watt incandescent bulbs. If you were to have all of these on at one time, you would be drawing nearby 20 amps of Dc power. In a few hours, your particular group 24 12-volt battery would be near dead. Even if you had two batteries, you wouldn't have much left to desist out a 2-day weekend without a battery recharge.

Now if you were to replace every interior incandescent bulb in this fictitious voyage trailer with a 24 Led array warm color lamp, each drawing 190 mA, the total power consumption drops to 3.8 amps, over 5 times less power consumption. You wouldn't likely replace every incandescent bulb with a 24 Led array lamp but you could and if you did, you would be using 5 times less power, even if you had every light switched on.
There are some different routes you can take when doing the Led lighting mod: individual lights, such as a night or reading light, all or some interior lights, interior and exterior, storage compartments, etc. Much will depend on you budget and coolness factor you are trying to achieve. Replacing every incandescent bulb may just break your piggy bank, but doing a few can still help save some battery power.
Using a particular Led for a night light, like in the bathroom, can be a real life saver. Well, it may not save your life but if you have to get up at 2am to go, you won't be blinded by the light and you should be able to go right back to sleep. A particular Led connected straight through a Spst toggle switch mounted on the bathroom light fixture can furnish just sufficient light to do your business.
Perhaps you just want to change a few lights out, like the lights over your bed, that are commonly too animated to read by. There are direct replacement Led lamps that wish no modification to the lighting fixture, other than swapping bulbs. For this type of Led lamp, use the "warm white" type. The cool white Leds furnish a bluish tint to the light color and may not appeal to your reading tastes. The warm white Leds furnish a yellowish light color very similar to that of a general incandescent bulb.
If you plan on replacing the main lights inside the Rv and have the type of fixtures that comprise two bulbs with a switch in the middle, you can replace just one of the bulbs to sacrifice cost. This way you not only save money, but you also can still furnish more light when you need it by switching on the second bulb. For this case, you should consider Leds that have a wide beam angle, at least 120 degrees. This is the angle at which light is projected from the lamp. The wider the better if you're trying to light up a large area. These lamps are typically configured in a flat holder with many Leds, as many as 36 in some cases. They plainly affix to the fixture with Velcro and plug in just like a proper bulb.
Another cool Led mod is to fit a Led rope light under your Rvs countertop. Many upscale Rvs have this highlight as a proper option but there is no fancy you can't have this classy look either. First, have someone help you test fit the rope for length, ensuring you have sufficient for the whole countertop. Then get some double-sided tape and stick it to the cabinet or under the countertop where you want the rope to run. If you have any left over rope, drill a hole the size of the rope's diameter and run the excess straight through the hole. Just stick the rope to the tape and press firmly. You can also add a switch to control the rope power as well.
A step light is also another easy Led mod that consumes very puny power. If you forget to turn it off, you don't have to worry since it can be on for days and still be easy on your battery. You can use a courtesy light or an amber side ticket light. These mount with a couple of screws to the underside of the stairwell. Power can be run to an inconspicuous switch inside. Some even have light sensors so they can automatically turn on when it gets dark and turn off in the morning.
Outside compartments are also a great candidate for Led lights. These can be powered straight through a pin switch so that when you open the compartment door, the light turns on, and then off when you close the door. The color of the Led light is not so leading as is the placement of the light. Compartments are commonly rectangular in shape, so try and place the Leds near the corners of the compartment. This way, you will get the most light to all parts of the storage area.
Finally, upgrading your Rvs face lighting can make for a very clean look as well as heighten protection going to the road. Led porch, marker, clearance, backup, turn, and running lights are all candidates for Led replacement. Fortunately for you, many companies, like Bargman for example, now make direct replacement fixtures that comprise all things you need to achieve the upgrade. Just be sure to budget sufficient since total face lighting replacement can run in to the hundreds of dollars.
Tip: Led brake/tail lamps may not work with some older thermal flasher units found on some vehicles. An Led brake/tail lamp will wish an electronic flasher/blinker unit which is commonly available at your local auto parts store. Just ask for the electronic equivalent of your thermal flasher.
