Hi, This should be easy for the users of this forum. I want to set up my jeep to use the stock tail lights for towing. Various places sell Diodes to Isolate two power sources (Jeep and Tow vehicle)But from what I know I should be able to buy a few Diodes for a few dollars and soder them together for a fraction of the price. What I don't know is what Diodes to buy. Jeep and tow vehicles are 12 volt. Currently the bulbs are Standard 1157 tail light bulbs. I would like to upgrade to LCDs at some point. Thanks in advance. |

LCDs? You mean LEDs.
What is a tow light? How is it different from a regular light? |

lol... your correct... LCD/LED... Posting too late at night.
Tow lights... Now when I tow my jeep I have to add another set of lights to the back of my jeep. I want to use the stock lights on the jeep. I can't directly wire the towing vehicle in to the Jeeps wiring because it would cause feedback to the jeeps systems. Here is a link to what I want to make: http://www.hidden-hitch.com/prod.asp?pc=38955 So I want to be able to power the Jeeps Tail lights by either the Jeeps systems or a Tow vehicles systems with out causing feed back to either system.

Doesn't jeep sell kits to do this? I have seen many campers do this when they tow their jeeps behind an RV.
EDIT: Didn't see the link the OP included... oops. |

Well, it looks like you can do this by using diodes. Put a diode in series with the light and the Jeep's existing electrical system. Now feed your signal from the tow vehicle through another diode connected directly to the Jeep's light. Essentailly it will look like a Y with two diodes forming the V and the light connected at the stem. |

You want generic rectifier diodes, not zener. Something that can handle around 10A at low voltages. |

So I don't know how to read all those specs. All the diodes I have found are at most 1.0A. Can you give me a part number? |

Here bro, most of us like to let people learn how to research things on their own so they dont come back with the same questions later, any ways since you tried, http://www.digikey.com/scripts/DkSearch/dksus.dll?Cat=1376383;keywords=10W%20diode some how the 1kV 60amp one is the cheapest, nothing can wreck that diode lol, enjoy |

Basically what he said. Any rectifier diode with a voltage rating of 50V or more and a current rating of at least 10A will be suitable. It's been a long time since I've looked stuff like this up, so my databooks are at least 8 years old. |
