Hi,

 

I bought the warm white 3mm leds from Evan Design:

 I found that in the Williams F3s, Sharks, E7s, and Scale GG1s, there is a cavity behind the lens of the headlight and the Led fits nicely in there. All you need to do is remove the shell, slip the led in the cavity, secure it with some tape, the led is prewired, just cut the led wires into the existing wiring for the bulb in the cab and your done. I left the bulb in the cab lit as it still gives a nice glow to the cab. I also added MTH crew figures to the cab, 3M double sided tape secures them nicely to the shell of the loco. 

 

The led headlight and crew figures add alot to the already nice Williams locos.

If wiring motors in series increases light brightness, how will that additional brightness in the lit cab look? Will it be overly, unnaturally bright for a cab? What if you also splice a 3mm led onto the wires going to that cab light, what effect, if any, will it have on the cab light's brightness? On the led's brightness?

I like the LED option. The existing cab-lightbulb in a Williams loco isn't going to be terribly effective as a headlight, since all the light it produces is being spread out in all directions, with some of it managing to leak through the headlight lens (and most of it through the cab windows--it's a wonder the engineer can see anything at night with all that glare ). 

 

An LED mounted in the lens gives it a light source that goes mostly in one direction--right through the lens. Lights up the track much better that way .

I would go for either the LED light or a lower volt light bulb for more brightness.

 

From my experiance with Williams engines, why would I want to re-wire the motors to series when most of my Williams run at a decent speed now? That for me would be like replacing a turtle with a snail, as far as speed goes.

Also I had to add a motor set to one of my diesel consists, an ABA Santa Fe, for more power to pull the El Capitan passenger set with better speed.

FYI, I am using a postwar ZW, a KW, and a Z, so there is plenty of power to the track.

The voltage will approximately double for the same engine speed.  Most complaints for Williams engine have been poor low speed performance.  Wiring the motors in series significantly improves low speed performance and is very simple to do.  None of my Williams engines have cab lighting, so I can't comment on that.  However, if the cab lighting does not have a voltage regulator, the brightness will also increase.

The "regular" bulb is this conversion is the MTH 6V 60ma bulb, which dissipates 1/3 of a watt.  No melting is going to take place.  If you put a higher current bulb in there, it might be an issue, but normally I use LED's.  The bulbs are what comes with the PS/2 conversion kit.

 

Painting the bulb won't really direct the light as intended in this particular case, since the bulb is far away from the headlight lens.  It probably would help, but it's hardly an ideal solution.
