Since then I have begun using sugar cubes so not so much surgery has to be done. Depending on which combination of decoder + speaker that I use, there may be a need to mill out the manufacturer's groove for the rear headlight. This is a late answer, but will be helpful to others. Aircraft in general are much more prone to vibration because the powerplants are much more rigidly mounted than in surface vehicles and the way the whole structure is constructed is more prone to transmitting vibrations. Chuck it in a drill and run it across a file until it's close. The same goes for hydraulic fluid. Aside: A little digging turns up a pdf on alkaline batteries from Energizer.

And if soldered connections are melted in a vehicle, that's the least of your problems and you should be completely replacing the wiring anyway. By sorting these wires out I know what has to go where. Fuels and hydraulic fluids are also toxic and really bad for bare skin, but again that's not the same thing as corrosive. You need rethink your approach. Which is also not near to 220 Ohm.

Resistors are usually available in values such as 10 Ω, 12 Ω, 15 Ω, 18 Ω, 22 Ω, 27 Ω, 33 Ω, 39 Ω, 47 Ω, 51 Ω, 56 Ω, 68 Ω, 75 Ω, and 82 Ω and their multiples, 510 Ω, 5.

If you search the WeHonest site you'll see pre-wired, two pin mini connectors. Those other resistors need to be 50 Watts because they have too little resistance. Each vehicle may be different, or may have been previously modified. You may need the installed light pipe for some of your installations. They will corrode, even if you cover them with electrical tape, and eventually the connection will degrade. Here, I used Kapton tape: The little bit of tape on the side of the weight also helps to reduce vibration noise from the shell walls.

Glueing something to the back of the hole is going to look weird. I have several that half the strand goes out. Ed, I always appreciate that you take the time to add some helpful photos! This fact, coupled with the fact that turn signals tend to be operated in short bursts, is likely why your 6 watt resistors are still working. I am probably wrong… but I chose to buy at RadioShack a 0. Therefore, select the next higher value of power rating.

Obviously it's 10 years too late for this guy, but maybe this will help a future reader. No matter what wattage resistor you have, it will see the same power. Just to summarize for the benefit of future readers 220 Ohm is used instead of 128 Ohm the calculated value because - 220 Ohm is a standard value and is easily available. Years ago many things were manufactured with plated copper contacts that were silver on the surface but copper underneath, but I haven't even seen anything like that for many years, and never saw it in crimp products available to the average consumer. Is there an accepted uniform color coding that red is always say + and black is always say -? Not ideal, but it works as a stop-gap until I can figure out why the flasher replacement doesn't work. Why is a resistor even needed, and how would you know what ohms it should be? The only saving grace you have, is that during a turn-signal operation, they are only on about half the time, which will dramatically reduce the heat dissipation required by each.

Most all of my engines are set up so both headlights come on when I press F0, with the light in the direction of travel bright and the reverse dim. Anybody who claims that others should take their word for something based on experience is doing so because it's the only thing they have when all the facts disprove their claims. No turn signal bulb is anywhere near 50 watts. If a small resistor would do, then you're drawing a small amount of power and it's no big deal. We will find we need a 4 ohm resister to get 25mA of current.
