Review on Upgraded Version 7440 7443 LED Strobe Brake Lights Bulbs - Pure Red Flash W21W 🔴 T20 Wedge 7440LL 7443LL 7443-SRCK, 7443-CK 7440ST W21W 12V Stop Lights - 2835 SMD for Cars, Trucks by Guerdon Draper

I've used them for 4 weeks with no problems. Then one day my dashboard started flashing and I parked. The car no longer started. I was halfway from LA to the bay. Had to tow it for 4 hours and it cost me $600 plus $200 for dealer repairs. Will sue Amazon for compensation. The dealer stated that these bulbs shorted out the braking system and prevented my car from starting. Update: After the dealer provided proof that they had shorted out my car's braking system, all the lighting took no responsibility. I was left with a full bill for a problem caused by their product. Don't take this brand.
