Njengoba i-p21w ehamba phambili ishibhile futhi itholakala, izimoto eziningi ziyayisebenzisa.

Yize izimoto eziningi ngokwengeziwe zisebenzisa ama-p21w led led manje, ngiphakamisa ukuthi kungcono uthenge i-p21w ehamba phambili nge-canbus.

Ngoba i-BCM yezinye izimoto ayihambisani nama-led bulb, i-canbus led p21w ingaxazulula leyo nkinga.

Amakhasimende wamukelekile eza ukukhuluma nge-p21w canbus eholelekile nganoma yisiphi isikhathi.
