Confirm you are replacing with correct bulb wattage.some times printed on the bulb holder.
Ensure the bulb / bulb holder are not loose in their housing.
Stand back from car and check all rear lights nearside / offside beams are same individual system at a time and all together.Please keep engine running take care when reverse is checked.
For interests sake swap the bulb from good side see how long is lasts.
