I searched this thread and sorry if i'm being repetitive. I recently tried changing out my trunk lights. I believe they are two 36 to 37mm bulbs on either side of the stock sub. When i change both out to LED's they start flashing every 3-4 seconds along with the bulb on the trunk door. When i leave 1 stock bulb and change 1 to LED it works fine. Anybody know the reason or solution. I even have error free bulbs that i tried and still the same result. Is it because the voltage is different from the LED and stock bulbs? THanks in advance
