how would i make the entity player give off light whe holding something?

i got this far

if(player.getCurrentItemOrArmor(1) != null){
		ItemStack hand = player.getCurrentItemOrArmor(1);
		if(hand.getItem() == Block.Torch){
			player.(give off light?)
		}
}

 

now my question is player. what?

you would need to make your own player light render because notch hasnt added that due to it causing mass amounts off lag from constant updates on both server/client
