About the Bicolour light panelized X4 PCB
Bicolour light panelized X4 is an open source PCB design by slonket, published on GitHub under the MIT license. It is a 2-layer board measuring 48.2 × 41 mm, with 4 components from 3 distinct parts.
By type, the board carries 2 diodes and 2 resistors.
From the project
An assortment of projects to supplement the Lego 12V "Gray" era trains.
The brick contains two red/yellow bicolour LEDs which change colour with input polarity. This brick is intended for use in locomotives/rolling stock to produce a headlight/tail-light changeover with direction.
- Identical formfactor to the original 2x2 12V light brick (08010bc01). - Version with 3-hole socket. - Colour change red-yellow with input polarity. - Improved brightness over original, particularly in the lower voltage range.
