when i switched to led lighting on the turn signals i found that the metro wiring polarity is reversed. you use a transistorized flasher (solid state) and make some jumper wires terminated with spade connectors. mount the bigger flasher package away from the fuse panel, reverse the polarity of the relay coil connection using the jumpers, and the hyper-flash problem is tamed. i noticed that even if you use the solid state relay, they still need a nominal resistance. i couldn't get a normal flasher rate if i used leds in all 4 corners so i used incandescent bulbs in the front turn signals and the leds in the rear. pay attention to the advice about using surface mounted device (smd) leds. they are the latest and greatest rendition of the led world and they are brighter, allowing for more leds to be fitted in a lamp assembly. the ones i used for the brake/ running light positions have something on the order of 84 individual smd leds on them. the ones i used in the turn signal position have something like 40 smd leds. those are considerably brighter than the oem incandescents while using a fraction of the current. |

What he said! I stand corrected on the resistor comment. I thought I read that. but the solid state flasher makes good sense! |

ahh did not know that about the reverse connection. I am surprised its relevant. 2 are power to activate the relay the other 2 are simply "completing" a circuit. I am surprise their polarity makes any difference at all. interesting. |

does anyone have a list of all the bulbs in the metro? i have been searching the web with little luck. i am especially interested in the bulbs in the instrument cluster, as some of mine appear to be out and i don't want to pull all apart to figure the bulbs out (i hate pulling that thing apart). if it's already been posted could you give me the link |

Did some looking up on ebay and google, Seems the SMD LED T10 (however many led's you want) Will fit a wide range of ares, 921 (Back up lamps) 168 (License plate, Front markers) 194 (Dome light) the price difference from US and Asia is enormous! like a 3-6x more. I am in no rush to change these so if I'm gonna save well over 40-50 bucks for all its worth the wait. They probably get them from over seas anyways lol. |

thx for bulb list. i read on autozone's web site that the tridon ep34 turn signal flasher is a fit for the metro and is also electronic and led compatible. check this site for bulbs http://www.superbrightleds.com/ Edited by richscudder, May 26 2012, 06:33 PM.

Just checked and it won't work if you go 100% LED (per reviews on Amazon) |

The cluster did turn out nice. Got a link or reference as to where you got them? |

How well do they dim?
Yes, from what I read in the reviews on Amazon
Found this link that shows how to modify the EP34 flasher to work with all LED's http://www.acksfaq.com/LED-turn-signals.htm Edited by JellyBeanDriver, May 26 2012, 11:32 PM.

nerys. since the relay is solid state, it has a timing circuit that triggers a transistor to control the flash rate. it does have forward and reverse polarity issues. that's why you have to orient the leads according to + and - . the geo just uses a different wiring configuration which has the opposite orientation of the relay pin out. when i converted my red resto-rod vert to leds, i replaced all the bulbs except the turn signals with appropriate led bulbs. i left the turn signal bulbs with standard incandescents so i didn't have to piddle with the flasher. here's the bulb replacement list for my 91 model: 1991 GEO Metro (With halogen capsule headlamps) High & low beam headlamp 9004 9004SU SilverStar Ultra: The brightest and whitest light.

i also want to point out that there a few pitfalls when you swap out some of the bulbs with leds. the front corner lights take 194 bulbs and most of the smd leds are too long to fit into the little amber colored domes. i had to chop the base a little bit and then carefully push and twist the bulb socket into position. it's an interference fit, even at that. some of the rear light lens sockets have limited space which makes led bulb selection critical. you don't want to go overboard with the smd led count or the bulbs are too long for a proper fit. in the rear side marker positions i had to use the older type leds instead of the smd type. there's just not enough clearance to deal with even the 5 smd "cube" style leds in that position. your best bet for the front and rear side marker positions will be inverted type gen 1 194 leds. the focused lens types will fit, they just light up "dots" on the plastic lenses. |
