I suggest the reason is contrast. Three lights as opposed to three brighter lights is little contrast. If you aren't looking at them the second the brake lights come on, you might not realize that they are actually on and that they are brighter than they would be with just tail lights. If you look at the tail of the car and four lights are bright and two are dim, you would likely assume that the bright lights are brake lights. ----- Original Message ----- From: "Mark McDonald" <tomswift@xxxxxxxxxxxxx> To: <mailing-list@xxxxxxxxxxxxxxxx> Sent: Saturday, June 28, 2003 2:26 PM Subject: Re: Re (2): IML: Fixing Govt mandated 68 bulbs They are now, but have they always been? This is beating a dead horse, but now I have to echo Chris's question: why? If it was not to insure that there would always be a working taillight, what was the reason? Why are 3 lights working as a brake light unsafe, but 2 are not? If I'm not mistaken, if one bulb goes bad in a chain, then that "kills" the lights in that chain. If you had 3 lights working as a brake light on the L, and 3 on the R, then that would mean 6 bulbs in the chain-- 2 more chances at bulb failure, possibly resulting in no brake lights??? I'm just trying to figure this out now that you've got me curious. Mark
