I have a 2009 hatchback and I'm trying to replace the light bulbs with LEDs. The 1157 compatible lights, as in brake/tail and parking/turn, don't seem to properly fit.

I have tested everything. All the volts are right. The positives and negatives are right. The new ones light up with my alligator clips like the old ones do in the socket. The new ones just don't light up properly in the socket. The brake pedal and the turn signal lever turn on the brighter setting. The less bright setting turns on when the bulbs are improperly installed, as in not fully turned in. This is both front and back.

The only difference i can see is that the contacts on the base of the new bulbs are oval. The old bulbs are circular dots.

Has anyone else had problems getting bulbs to make contact?
