Hi Dave,

Be sure you get the package with 5 3030 SMDs facing out and a
ring of 18 4014 SMDs Auxito has more than one 1157.

I found that knowing the LED potential isn't enough since they need to control
heat. A husky heat sink is integral with how hard they drive the chips.
It seems they run them up to 50C with the maximum being 75C

I got a set of cheap 1156 white with 10 pcs 3030 SMD and there was no husky heat sink and they were a disappointment (for brighter backup lights)
They needed to run very low current with no husky heat sink.

The white 1156 with the same chips was maybe $12
It makes a powerful backup light.
and the red 1157 $14 - which I tested in a 940 housing to measure relative brightness vs a standard 1157 through the red lens, using a light meter.

Have you tinkered with LED headlights yet? It's hard to select an LED
with the specs given by merchants being all over the place, many are absurd
liars, claiming 10 KW LEDs 1,000,000 lumens only $13.99 BUY NOW Last One!

Ebay and Amazon allow this ongoing deceit with fraudulent specs.

Cheers, Bill
