Yes, you would create a dead short and blow the diode or branch fuse. All LED's have must have an appropriate resister to limit current flow through the diode.

Quick followup just because someone is going to tell me I'm wrong. It is possible to use an LED without a resistor but then you must incorporate a current limiting circuit which simply replaces the resistor. In other words an LED is not a light bulb with a resistive element. So without a means of limiting the current the LED will blow. The most efficient LED's do not use a "resistor" but more sophisticated (creating less heat) circuitry than a plain resistor.

I got mine from here 1x T10 194 168 921 194 Bulb Lamp 12-5050 SMD LED ,Warm White Y | eBay . They are cheaper if you buy a 10 pack. Out of 20 I bought, only one doesn't work and it was my fault. Where the board attaches to the connector, it is very easy to bend. I have had these all summer and they are as bright as the incandescent bulbs they replaced. I have left a dual light on for hours and i can keep my hand comfortably on the lens. I have some LED's from CW that get much warmer than these.

I replaced all of my halogen puck lights (60 of them) with disc LED (Warm White G4 24 SMD LED) from newkitty1116 on ebay. Cost was $59.40 for the bulbs and $48.05 for the shipping. Came in about 2 weeks, as ordered.

So far I have had 2 defective LED's, both to do with flickering.

One caveat, if your halogen switches are the 3 position ones (high, low, and off) these LED's do not work on the low position. The low circuit delivers 6 volts, and the bulbs require 9 volts, minimum. No big deal for us as we rarely used the low position anyway.

Bottom line - one HECK of a lot cheaper than $20 per bulb from US distributors.

Does anyone know of a source for American -made LEDs for rv's? China gets enough of my money. I'd rather spend a little more to support jobs here.

I'm interested in the led conversions too. To try it out, I got one off of ebay for the porch light. It's got 68 smd led's on it. Hopefully it's bright enough and not to hot. The 1141 bulb melts the clear cover when it's on for a while.

I have a 1156 LED for a porch light and it's bright enough for me.
