trying to convert brake lights to leds

ok so i bought the lil cheapo led brake bulb from pepboys. the socket for my bulb has 2 prongs on the left and right and so does the stock bulb. the led has one prong in the middle so i bent one of the prongs in the socket so it would connect. now, when i depress the brake, all my dash lights light up? wth is this? the bulbs r crap neway and i will b bringing them bac, just thought i would share

Not all brake lights are created equal. You purchased a single element type bulb. Your car requires a dual element type bulb. The second element is the tail light. When you hit your brakes (since you modified the contacts on back of the bulb) the voltage for the brake light is now feeding power to your taillights. This is turning on your dash and also your front parking lights. Since we do not know what kind of car you have the following is an assumption. You purchased an 1156 bulb and you needed an 1157.
