sim lim tower got tri colour led, multiple blinking colours led, ultra bright led etc. Just go there, 3rd floor and look around the shops.
multi colours one are slight more expensive then single colour ones, round dollar plus or 2. Single colour ones couple of cents for 1. Ultra bright one cost more, but overall still cheaper than buying online.
Multi colours type got those blinking and non blinking type, either it be indicated or just ask the auntie to test. They have led tester behind the counter to test one, for some of the shops i used to go to.
hehe, how did the led blow? No limiting resistor or the positive and negative lead of the led tum balek?
