if you are thinking about doing this mod just remember the phasing and a few other things. when you look at your old leds you will notice one corner notched out. there is a reason for this. LEDs only work in one direction of. Change them out one by one and always look at the phasing. if you are new to soldering change out one at a time and check it to see if it works. just plug it in. the leds also run in series so if you didnt get a good connection/ phased wrong/ or bad led you will know.
