Hi Fred,
Please state exactly what you want the LEDs to do and for how long for each session.

Why use a 555 timer? To flash the LEDs? To time them out? If it is for a brake light then it sounds dangerous!
Besides, white is usually used at the front of vehicles, not at the tail.

What kind of battery and size? Lead-acid? AA Alkaline cells? Rechargeable Ni-Cad or Ni-MH?

How much dimming can you tolerate when the battery runs down?

My Ultra-Bright Chaser project would look cool on a bike and runs for weeks with just 4 AA alkaline battery cells:
