,This is a duplex system that transmits two signals: STP and ST1-.The ECM Uses these signals to monitor the brake, whether or not the brake system is working properly. There ‘s only one signal to be detected at one time, this is either signal which is indicate the brake pedal is being depressed or the signal which is indicate that the brake pedal is being released. If the both signals are detected simultaneously, the ECM intrepets this as a malfunction in the light switch and sets the DTC. The Wiring Diagram below shows the Toyota FJ Cruiser Stop Light Switch Wiring Diagram.

Horseshoe Magnetic LED Night Light
Xinhua Ming design this LED magnetic night-light was inspired from symbol of luck horseshoe, the shape brings a freshness to the stone bedside lamp. One end of it is equipped with a built-in battery charger plug the other end is a USB connector, in addition to providing power to the lights, but also it can charge mobile phones and other digital products by the USB connector.Are you still looking for the bright night light, get it!!

Build LED Light Pen Schematic
Physicians and repair engineers often use small light pens for visual examination purposes. Rugged and expensive as these pens may be, their weak point is the bulb, which is a ‘serviceable’ part. In practice, that nearly always equates to ‘expensive’ and / or ‘impossible to find’ when you need one.
LEDs have a much longer life than bulbs and the latest ultra bright white ones also offer higher energy-to-light conversion efficiency. On the down side, LEDs require a small electronic helper circuit called ‘constant-current source’ to get the most out of them.
LED Light Pen Circuit Diagram
Here, T1 and R1 switch on the LED. R2 acts as a current sensor with T2 shunting off (most of) T1’s base bias current when the voltage developed across R2 exceeds about 0.65 V. The constant current through the white LED is calculated from
R2 = 0.65 / ILED
With some skill the complete circuit can be built such that its size is equal to an AA battery. The four button cells take the place of the other AA battery that used to be inside the light pen. Link
