    Hi!

    Yes the LED got brighter with brakes but not at the ratio of the original 5W/21W bulb.
    (now that I got them out again,I will go measure wattage on each circuit of the LED and report back later for some clues)

    If the 3rd brake lamp wasn't so brutally bright, blinding the camera we could see the difference on the pic.

    I bought some high power leds from ebay. They don't light up as much as original. Maybe I need to check the wattage.

    I've bought LED lights a few years back to replace tail/brake light bulbs, but just going by my eyes, it looked like the incandescent lights were brighter. The same was true for the dome light I wanted to replace.

    With that said, I may have to buy new ones with today's technology. Hopefully better light output.

    That's a great idea, but I sincerely hope that those lights are running off a low enough current that the leads don't get too hot sitting on that Electrolytic Capacitor as that would be begging for heat related leakage.

    A little late to reply but if the above comment was meant for me then here it is:

    The blue thing is a resistor not a capacitor. Current draw is 51mA. While the resistor is probably 1/4 Watt rated and the assembly draws about 3/4 Watts,yes I am over taxing the resistor above it's rating however it has been almost a year and they have been working flawlessly.

    You've had these installed for over a year now. How are they holding up?

    The 2+2 in the headlights(park and corner markers) flawless. Dome lamp.trunk lamps also great.

    Tag lights not so great. I noticed one night while checking them that one of them was not lit so I started banging on them and with every tap I got a different combination between the two lights being on or off.

    So I took out two factory made 194 replacement LED bulbs from my now retired mazda protege's rear side marker lamps and put them in for my tag lights on the mirage.

    They are now so cheap on fleabay that I feel silly for soldering these up myself.

    The factory bulbs draw 388ma. I replaced them with two LED's at the front parking light position. The LED's draw only a small fraction of the current and they "flicker" when the lights are on. I am thinking that I need to install a 40 ohm shunting resistor across each LED.
    so that the circuit will "see" 388 ma. Do you think this will stop the flickering?
