2021 Spyder RTL. I tried installing LED rear signal light bulbs from Superbrite LED's but could not stop the hyperflash (very rapid blinking) using the Lamonster method. I found LED bulbs WITH built in resistors and the correct BAU15S base. PITA to remove the rear body work to get at the bulbs, but well worth the $30 for 2 bulbs. BTW, a 7/32 socket can be used instead of the 5.5mm socket called for in the DIY instructions.
