I wasn't happy about not being able to see the front red marker lights on my tinplate 260e. So I made this little gizmo using 2 3mm red LED's and 1 5mm white LED for the headlight. As you can see from the pictures, I believe this to be an improvement. You cannot look into the headlight, it will hurt your eyes. Since I couldn't see an easy way to pull power from the track, I thought I would make up this gizmo using a burnt out bulb. This screws into the headlight lamp socket. I also now have the ability to turn on and off from the dcs remote.

 Here is a question for the MTH tech gurus out there.......Does anyone see any issues doing this from the engine lighting board? I tend to think it is OK since LED's pull less power than an incandescent lamp. I checked amps on the 2 (screw in lamp, LED's). The LED's pull .1 amp while the incadescant lamp pulls.2 amps.

 Check out the pictures and let me know what you think.

I'm a bit concerned that 3 standard LEDs draw 0.1 Amp (100 mA).  That's an average of 33 mA per LED which might be driving them a bit hard.  Hard to tell from photos but the red markers seem a bit too bright (over-driven)?  Not sure on your "circuit" but I'd think you could cut current in half thereby operating each LED at less than 20 mA.

I was thinking the same on a Lionel E6 Atlantic.  Both rear and front markers definitely could use something brighter plus both headlites are lame incandescents.  I need to go back in to adjust the cherry switch for the chuffer anyway so why not?  I doubt there could be any permanent damage done as long as removal of the existing bulbs isn't a chore.

These LED's are from our forum sponsor Evan designs. They will operate at 8-25 volts AC or DC. The LED's have the necessary components to operate at the 8-25 volts. Not too sure what voltage is at the 260e engine headlight socket.
