These are the newest 3157 dual color RED/RED LEDs we have in stock. The 30W of power and 2800lm makes them the brightest RED LEDs you can use to replace the existing OE 3157 27W incandescent bulbs without the use of resistors. The lens at the top of the bulb allows for red light to pass through it.

NOTE: RESISTOR USE
One customer reported that on a 2005 Chevy Impala and a 2007 GMC Sierra 1500 hyper-flash occurred after installing these bulbs, indicating that resistors are still be needed. Please read the review.
UPDATE: the above customer used 50W 6 Ohm resistors on the 2005 Impala's tail light and got them to work without hyper-flashing.

Results Dependant on Application & Setup
First off, these 3157 equivalent LED's are definitely much brighter compared to the stock incandescent bulbs so that's great. And first impressions are that these are definitely well constructed. Yet in my applications hyperflash was still an issue, nope not overly surprise with my results as kinda anticipated such. First application is a 2005 Chevy Impala that's already equipped with front marker/signal switchback LED's (white/amber). Yes they're Canbus ready w/built-in resistors functioning perfectly fine as standalone's. But once these red LED's were added into the mix (rear marker/brake/signal) hyperflash was induced. Obviously when used in conjunction with the front LED's the built-in resistors don't provide enough of a load to combat the hyperflash. Second application, 2007 GMC Sierra 1500 which uses 2-bulbs per side at rear for marker, brake & signal lamps. Hyperflash is induced while signaling left or right with marker lights on, w/markers off no hyperflash. Would have liked to have tried an LED flasher unfortunately neither of my vehicles use the old-school type flasher relay so not an option. Time for Plan-B since the plug-n-play apsect wasn't to be. Will order/install some load resisters in hopes of eliminating the hyperflash.
