The optimal volt feature of 12 V is used for every other lamp in Civic. You can’t drive your Honda Civic with badly working stop lamps. You may need only BAY15D SBC type of lamp fitting and note the power limit at 21/5 W. Lights are immediately on for 1998 vehicles with engine code D16Y5. Actually Honda installed quite optimal light bulbs on cars with 1.5 type of motor. These dimensions will help Honda Civic 1.6 stop light to work efficiently.
For 1992 model year vehicles you have to use only BAY15D SBC type bulbs and keep voltage at 12 V. Be careful at buying any other lamp for Civic 1.4 than recommended by Honda. For 1.4 engine cars having model motor code D14A1 it would be bad idea to install more or less than 21/5 W capacity lamps. Any other types of bulbs will be destructive for 1996 Honda Civic electricity module.
