Thank you guys for the input. In the end it was just one of the tabs that was slightly out of place and not making contact. Looks like you have to be careful putting in a bulb, cause its somewhat easy to push that one tab out of place.
The info on the load equalizer is helpful, thank you. Turns out the brake module I bought has one included, but sadly the LED bulbs I bought do not fit under the lens cap. They are about 3mm too long. Sad. They are really nice bulbs. Does anyone know by chance, if there is an aftermarket clear lens? Maybe a dome shaped one? I did see one online, but it was a screw in type, so I doubt it'll fit my bike.
