Led Lights

Upgrading our lighting to LED bulbs. Have most of them installed. Trying to replace the RG 1141 bulbs. Was asked the polarity because they have 2 polarities for this bulb. I told her that all I knew was that the Denali TT 2006 was negatively ground. Can some one explain this to me. I know if the light doesn't light the first time I install the bulb, that I should flip it over and it should work. Is there something else I should look for? Sort of new at this.

An 1141 bulb is just a normal bulb (BA15s base) with a single contact center tip, right?. All 12v sockets that I'm aware of for those are positive in the center and ground on the sides. Reversing an 1141 bulb (or LED) won't have any effect; it will work regardless. A BA15d base, on the other hand, has 2 contacts on the bottom of the bulb, and an LED bulb for that WILL need to be installed correctly, as will 921 wedge types. If it doesn't light up, remove and turn the LED assembly 180 degrees.

Here's my conversion.

My MH used a lot of 1141 bulbs. I have replaced them all with LEDs. Only one socket was wired with the positive and negative wires switched. I switched the wires so the positive was on the single contact and all was well.

If the bulb doesn't light check the polarity with your multimeter and reconnect the wires if the center contact isn't positive. Oh, you don't have a multimeter, then just switch the wires and see if it works. You might try another bulb just to make sure it isn't a bad bulb.

Is the purpose of this mod more to save energy, or to get brighter lights?

I believe most do it for the energy savings, particularly if they do a lot of dry camping, though you can also get brighter, but then that uses more energy as well. One of the primary benefits for us, since we don't dry camp much, is that in two years since switching we haven't replaced one bulb while in the past we were replacing five or six fluorescent bulbs and a couple of G4s each year.

Energy savings and reliability. I dry camp a lot and the LEDs help a bunch in that regard. I also had lots of bulb failures, in particular with halogens in the ceiling and the exterior "porch" light. I haven't replaced one since I upgraded two years ago. The ceiling lights are indistinguishable from the OE lights in color or output.
