Review on Auxbeam 1157 LED Bulb 6500K White 300% Brighter Mini Size 5-Minute Plug-And-Play 2057 2357 7528 BAY15D Halogen Replacement 1157 White Bulb For DRL Parking Light Backup Reverse Light Tail Light by Mark Loredo

Installed in a 2018 f-150 STX 3.5L. Using them in the tail lights that double as blinkers. Pulled the old bulbs out, put the new ones in, and geeeez they are bright. Everything "works". While they physically blink correctly, the blinker indicator on the dash blinks in hyperflash, as if a blub was out. Everything else works great. Not too sure what the "Error Free" tag means, but I understood that it will not hyperflash or otherwise give a bulb out warning. I have aftermarket LED headlights (hi and low beams), fog lights, and reverse lights, with front blinkers on the way. However none of that should interfere with these, so I will install some load resistors behind the tail lights, and see if that fixes the hyperflash on the dash.
