Vehicle LED vs halogen energy consumption?

I'm noticing many cars now offer LED tail lights on higher trim levels such as the 2014 Honda Accord or Chevy Malibu

So I know there are a lot of benefits to having LED over halogen bulbs such as bulb temperature is cooler, lasts longer, brighter, draws less energy etc. But many automobile tail lights that use LED have many more bulbs rather than the one or two halogen they replace. Do these LED together still draw less power than halogen?

Please explain thanks.

Interesting. You are saying a 13 LED Caddy taillights vs 2 1157 bulbs.

1157 will use 5w-21w || 2x=10w-42w
LED may use.25-1w ||13x=3.25w-13w

not sure on the wattage used on the LEDs

LED's;

- draw less power than a similar glass bulb
- are brighter than a standard glass bub
- last longer
- are considerably cheaper to produce
- are more vibration resistant
- are cooler running

Yea, they will grow tired if it when electroluminescent panels come into popularity. LEDs of good quality will last longer than bulbs. They also brighten faster than a light bulb so the people behind you get a slightly faster notice.

It has NOTHING to do with "energy conservation" Your car's alternator is capable of putting out much more energy than is needed for "normal operation".

LEDs are just a styling fad… Something new for the designers to play with. They'll get tired of it eventually.
