I picked them up at The Retrofit Source https://www.theretrofitsource.com/h11-led-headlight-bulbs-morimoto-2stroke.html. Price was 120.00
I have not driven much at night yet so cannot comment on overheating
I just installed a set of Morimoto 2 stroke 2.0 also. Very quick , Painless install. Also installed a set of Hikari high beams as could not pass on the price. Time will tell if it was worth it
