Title: 2-6-6-2 headlight
Post by: sedfred on February 16, 2017, 06:02:30 PM
My 2-6-6-2 H4 arrived after over 2 weeks! It runs great but the headlight is a little disappointing, it's orange, oranger than Donald Trump's face lol. Jokes aside, is this normal for the 2-6-6-2? How hard is it to replace the bulb if so what would you recommend?

The question is , is it a bulp or a LED?
If it is a LED just replace it with a white emitting LED .

Re: "white" LEDs-bear in mind that "Bright White" usually has a bluish hue to them.  "Warm White" more of a yellowie glow to them.  You may like that look better than Bright White.  If you ever did get hold of Bright White ones, you can get them to have a yellowie glow by dabbing a little bit of  Tamiya Clear Orange X-26 acrylic paint on them.  If you don't get it right the first time, you can wipe it off with alcohol and try again or try wiping some but not all the paint off.  You can test the color using alligator clips attached to your pack or track and to the LED and resistor.  Before you paint, you can make the LED "diffuse" by rubbing some fine grit sandpaper on the resin of the LED, if the ones you get are not diffuse.

And keep in mind, if replacing a bulb with an LED, you will need a resistor to attach to the LED + leg before powering up.  1/4 Watt ones are smaller and good for tight spaces and depending on how bright or dim you want the LED to shine, will dictate how many OHMS you will want your resistor.
