Constant current LED brake light tail light module. Ever wonder how to make your filament bulb type tail / brake light to all leds, the solution is to use a constant current led driver with additional mosfet as switch for brake light so that the usual tail light will switch from dimmed to full brightness on the leds. More often, enthusiast uses just again the limiting resistor type of controlling the brightness of the light emitting diode installed on the bike, as i had said from all of my previous post about led, in order for them to stay consistent and works longer, a constant current driver will protect your led installed.

Led headlights are beginning to emerged from the open although there is still no true led headlight available in the market, they are still on the experimental stages for beam, focus, reliability, and if there was, it will be expensive.So why not experiment with leds and come up with your own. Using one Ic and some discrete components, you can do so.

The MAX16819/MAX16820, step-down constant-current high-brightness LED (HB LED) drivers provide a cost-effective solution for automotive interior/exterior lighting, architectural and ambient lighting, LED bulbs such as MR16 and other LED illumination applications.

The MAX16819/MAX16820 operate from a 4.5V to 28V input voltage range and feature a 5V/10mA on-board regulator. A high-side current-sense resistor adjusts the output current and a dedicated PWM input (DIM) enables a wide range of pulsed dimming.
