| Re: LED Bulb Conversion
Ok, I decided to try some LED bulbs for my brake / parking lights and my turn signals this weekend. On 97 Catera, it has this one plastic bulb mount for both bulbs in each lens. There is total of 4 wires running to the bulb mount: park, brake, turn, ground. This is what I found:
Brake / Park are the correct polarity in the socket. Plug and play (I think). More later on that.
Turn is OPPOSITE polarity in the socket. The common of the brake / park bulb (the shell) goes to the single pole of the turn bulb.
Since this is a solid piece of metal, the only way I see to properly reverse polarity is to cut the metal and solder the correct connections (simply swapping wires cannot work as the shell of one bulb and the center post of another bulb are using the same piece of metal??)
My third brake LED is not working. However I did not notice if it was working before I started. I did swap back to the original bulbs to eliminate the possibility that the LED bulb was causing a problem.
I have more investigation to do. SInce I didn't see anyone mention this, then...that is what i see, and if anyone else noted this problem with the socket polarity - can you enlighten me on how you corrected it? (97 thru 99 I assume, I didn't note any 2000 and newer having any issue). |
