I ordered a pair of red led 1157 replacement dual intensity "bulbs".
Here is a link-- 2pcs 1157 BAY15D 18 SMD Red CANBUS OBC No Error Signal P21/5W Car 18 LED Light Bulb 12V-in Light Source from Automobiles & Motorcycles on Aliexpress.com
They are not dual intensity so can't be used as tail/brake/turn lights.
They are supposed to replace 1157 which IS a dual filament bulb.
They aren't any brighter either.
I'm out $5 for the pair. I knew it was a gamble.
Save your money on this one.
There are other types LED replacements out there but I'll stick with my
old incandescent tail lights for now.
I also ordered T10 led replacements for my landscape tier lights and
some inside the trailer lighting.
Those have not arrived.
I have more hope for success with them.
I'll post here with results when I receive them.
