LED voltage specific ?

Post by 3 bike mike » Sun Jan 07, 2018 4:05 pm

Hi. Thinking to upgrade my MT9 running on 6 volts at the moment, most bulbs ( not headlight ) are LED bought as 6volt . But If i upgrade to 12 volt will I need to change the LEDs or will they just be a bit brighter.
Many thanks for your anticipated advice.

Most DC LED bulbs will blow instantly when powered by double voltage. There is just a resistor and LEDs inside. No voltage converter like in AC household LED bulbs.

LEDs are voltage and polarity specific.

Well, some LEDs made for auto use have a range of input voltage that they will tolerate, and we have no idea yet what yours are.

Many of them will operate from around 8 to 9 volts up to around 15-20 volts because they DO have a voltage regulator chip in the base of the LED. Others do not have that capability, so it just depends on what you have.

If those LEDs are made for 6v vehicles only, then they will probably glow really bright on 12v, for a second or two.

If so, then it's time to install 12v LEDs.
