My rear light warning light is turned on now. It was just 2 bulbs on the high mount stop light. I replaced with 2x 194. It said something like 5w. I thought they are the same. now all my lights light up at the rear. Could it be just the 2x 194 or other issues?

 

Koito is the factory bulb manufactuer. Best to replace with same exact bulbs due to the resistance of aftermarket bulbs . Check other lights to make sure they are in working order. Might be the tail light sensor? Although unlikely.

 

It may be wrong bulb...The real bulb should be 2825 with 5watt vs this 194 only have 3.78 watt....wtf... I am going to buy some 2825 and replace it and let you guys know. but for 1.22wattage difference.....

 

Any remedies?

 

confirmed that changing the 5w and warning went away!!!! amazing!!!!
