As a follow up - I installed a set of the Walmart Pilot 1157 LEDs in my old Corvette today. I now realize that the 3 LED groups on the top or end of the bulbs are the ones that light up for brakes and turn signals. the LEDs around the bulb barrel are the ones that illuminate for tail lights. That works great with bullet type tailights like the Corvette or the round lights if used on the rear of a Cobra. My ERA has rectangular lights on the rear which means the LEDs for the brake and turn signal are pointing up into the top of the light housing - rather than directly to the rear - thus the reason they didn't seem especially brighter on brakes or flashers. On my Corvette, since they are pointing out the rear, they are very bright.

For a Cobra replica with the round tail lights these are a very cost effective way to get LED tail lights - costing around $30 for 4 bulbs. I doubt they can be distinguished in brightness from the Superbrightleds which cost roughly $100 for 4 bulbs.

For rectangular tail lights they are not quite as good but OK - at least on brake and turn signal brightness.
