A diode is a just a "one way valve". You'd need to use a resistor to lower the voltage.

Not true.

Actually, it IS true. A resistor is used to lower voltage, while a diode prevents voltage from flowing one way and allows it to flow the other way.

For posters that argue, just post the Definition. Doug

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors may be used to reduce current flow, and, at the same time, may act to lower voltage levels within circuits.

Instead of asking for a warranty extension(I doubt Newmar would agree to that), ask Newmar to replace that fixture with another type with replaceable bulbs. Most times, OEM's will allow a customer to purchase the fixture they want and then reimburse them the cost. This accomplishes 2 things.
1. It fixes the problem
2. It REMOVES that complaint from Newmar to the customer on that appliance. The customer is now responsible for the operation and warranty of that appliance. Doug

This is really a very odd problem that typically doesn't happen. Have you posted on a Newmar forum to see if others have had the problem? IRV2.com has such a forum. Good luck!

You're going to have to explain that comment. The most common function of a diode is to allow an electric current to pass in one direction. A resistor is a electrical component that implements electrical resistance as a circuit element. Resistors may be used to reduce current flow, and, at the same time, may act to lower voltage levels within circuits. Since you commented that what I said was untrue, please enlighten me so I may be no longer in error. I guess I've been using resistors and diodes incorrectly for 40 some years now.
