[Thumper]

Ok you Hummer lovers so here it is, I just finished installing rear bumper lights on my 03 and since I do not know what the normal function of the lights are, I need verification that they are working as they should because its a little different than what I expected.

When driving during the day (without out headlights being on) the bumper lights act as an additional stop light and turn signal.

When driving at night (headlights switched on) the bumper lights act as additional driving lights but when the signal light is activated they do not blink and when I apply the brakes they do not brighten.

Are they working properly?
Thanks for your responses in advance
