Options for Replacing Incandescent Bulbs with LED Equivalents to Reduce Power Demand

Question:

I want to upgrade my 5th wheel tail/stop lights to Led. My present fixtures are Optronics AIST01. I am looking at Command Electronics 328-003-81BM1 and 328-003-81LBM1. I notice there is a small difference in height, but shouldnt be a problem. Otherwise would these fixtures be a suitable LED upgrade? Also are there any other issues to deal with when upgrading from incandescent to LED? Thanks for your help.

Converting an RV to LED lighting is a great way to both make it more visible and to reduce the power demands on your tow vehicle wiring setup. I have an alternative suggestion that you may like since it might save you some money and installation time.

We have LED equivalent bulb replacements like # AR50368 and many others that can replace the most common incandescent bulb types. These offer a simple way to upgrade to LEDs without having to replace the entire fixture and this route often costs less than whole new lights. All you need to do is determine the incandescent bulb number used in your lights and then select the appropriate type and color of LED "bulb".

The linked page displays all of these items; just click on your bulb number(s) in the margin to see the LEDs that will replace that bulb. You will want to use an LED of the same color as the lens that covers it; so use a red LED such as # P230921R360 for a tail light and a white LED like # DI85VR for a reverse light, etc.

I suggest also installing a load resistor on each turn signal circuit since sometimes hyper-flashing can occur (very rapid flashing of the turn signal) when an LED replaces an incandescent bulb. You an use part # DI34ZR which is a set of two.

If you prefer to mount whole new lights # 328-003-81BM1 and # 328-003-81LBM1 that is fine but you will again need the load resistors on the turn signals.
