    Has anyone modified the lighting for a Kato SD40-2? I'm trying to model several Canadian units, where the lights are located on the nose. I'd appreciate any input from someone who has changed the lighting system on these units. Thanks.

    If you are referring to the problem that the lights have a blue tint you can fix that by putting a thin coat of yellow paint over them.

    I have done this in N scale by using fibre-optics. In HO you may have space to move the led, and connect with wires to the original mounting point.

    A new headlight casting would be needed, I guess with new lenses. I would make the lenses with fibre optic.

    What do you HO guys do?

    <font color="336633">until now i have always used 1.5v micro bulbs in the headlights with 6 diodes to give constant directonal lighting,but as im now going dcc i will have to change all these for 12v bulbs.... </font>

    Has anyone seen the heat a 12v bulb generates? I'm scared to put one near a Cannon cab...

    Anybody have anything else on this?

    <font color="336633">Eeeeeeeeeeeeeeeeeek! i didnt think of that i supose i could use 6volt bulbs and put a resistor in it, i will have to think about that and do a bit of testing b4 i go al out and refit all my locos </font>

    I'll have to do some testing as well...

    <font color="3333cc">You could, of course, use two fibre-optic cables for the lights, back to the bulb away from the shell. In my HO days I used to put the bulb in a short piece of brass tube, and the two fibre-optics in the other end. It worked fine, and the bulb could be some way from the actual hood.</font>

    You guys have to use some kind of heat sink. Usually a little electrical tape around the bulb and possibly mounting some plastic inside the cab could work. I use 12v bulbs extensively in HO scale and have had no problems so far as long as I do this. Of course, none of the bulbs touch the plastic, and never will due to where they are secured (against the lead weights for the loco).

    The metal tube and resistors seems to carry the heat away OK. Have no problem in HO. It might build up on a long run in an N diesel, maybe? With DCC you can always turn the lite off.

    I'm thinking a big tube for a light channel/heat sink should work. But with most of the BNSF units going to the nose lights it shouldn't be a problem...
