If you were to ever replace the actual lower brake lights I believe you'd need the 1157'*..
I have 3057'* for my brake lights also, if those 3457'* worked that well for you I may consider getting them, I can get 2 for 9.00
The good LED'* are pretty costly, found 60w LED and 80w LED'*

Turn Signal Brake Lights
"" Application: Turn signals ( Need 50W 6ohm load resistors) Brake Stop Tail Light
80W is not the real power consumption. Each bulbs contains 16pcs 5W Epistar LED chips. The real power consumption is 9.6W. Should be the brightest 3157 Red LED bulbs in the market""
I am pretty sure you'd need the load resistors for the turn signal lights, so you do not have Hyperflash..
I don't think I'd use those splice connectors that come with the resistors though, I'd rather cut the wire, twist the wire ends and solder the wires up, then heat-shrink wrap them.
NOTE: Just noticed the brake light / turn signal lights that came up when I searched for the brighter LED'* were the same...
Looks like 65.00 to replace the 2 brake lights, and 2 turn signal lights, sheesh... I think I like the 9.00 option to replace the 2 reg brake lights..
