It's almost as Mazda said, how do we make the non-GT model rear tail lights looks as pathetic as legally possible by DOT laws? Then they design the Sport and Touring tail lights for the 2017 & 2018.
That's the first thing I changed on my Touring. LED tail light bulbs and LED license plate lights.
I pulled the existing bulbs from my 2018 CX5 Touring and they are dual filament incandescent bulbs - one filament for the tail lights and one for the brighter brake lights.
For those of you who have replaced these with LEDs:
1) Did you use dual LEDs (that support two brightness levels)? Maybe I missed it but it doesn't appear that the Diode Dynamics bulbs are for dual use.
SuperBrightLEDs.com sells dual 7443 LEDs for around $10 each - maybe not as bright as 500+ lumens but still bright and much less expensive...
2) Since we're replacing incandescent bulbs with LEDs, did you get the diode unit to prevent fast flashing? If not, they work fine without these?
2 - One doesn't need the diode since these are not turn signal LEDs but just brake light LEDs.
I've ordered these 300 lumen cool white leds and will let you know how they turn out:
Does it make sense to replace the incandescents with the OEM LED bulbs that are used in the GT. Would it not be plug and play? Does anyone know the Mazda part number and cost?
I know this is a totally noob question, but my tail light got hit by a car, the whole enclosure is cracked though the lights still work. I have a replacement part which looks like it really only needs to plug in but I can't figure out how to get into where the plug is. I've taken the two screws off and can unlatch the old enclosure but how to I get access to the plug?
