The ones in your link won't work for two reasons. One is - as you have seen - the light control module will not recognize them and second, they will have the totally wrong light pattern. They are fog lights, made to be low and wide. You want high beams, i.e. long, not wide.
Apart from that, do you run constantly on high beam?
Apart from that, do you run with you volume up to 11 all the time?
Apart from that, the regen will feed up to 10 kW back into the IMA battery, not into the 12 V that you use for your lights and onboard electronics.
I would suggest, you go for a beefier battery (i.e. 151R) and/or use capacitors for your audio to smoothen the flow.
