    Has anyone made a switch on their 308 from the stock reverse light bulbs to 50 watt halogens? Italiancarparts offers a pair of bulbs that can be installed without circuit modification. I was wondering if anyone knew the bulb information. Their catalogue price of $30 plus $9 for shipping means local cost should be around $20.

    Stock bulbs are 21watts each, upgrading to 2 - 50s, will add 58 watts or about 5 amps to the lighing circuit, wiring should take it but Ferraris are known for sub par elec. systems. fuse box connectors should be checked for any heating.

    The reverse light is not used for very long periods of time, but would the additional heat of a 50 watt bulb cause any problems to the lenses?

    First Question:
    Why would you? There i no need to light up the neighborhood when you drive out of your garage.
    On my 840BMW I have burned the wiring harness with the halogen bulbs that were higher than the original lights. I can only advise you NOT to from experience.

    I did this a few years back with no neg. effects. I got the bulbs at an auto parts store and I seem to recall it only cost about $8 each. Works great.

    What Martin said.
    You haven't lived until you've seen smoke coming from a lens or harness. And you need to see it. Otherwise...

    Wax until you've owned a few Jags you can't appreciate wiring. You know Lucas (the prince of darkness) and the problems they have had. Make Ferrari look good. Check your connections and convert your fuse block and you should have no problems.

    Don't do it! If, by accident you leave the car in reverse too long (not sure how long might be too long..) you WILL melt the center "clear" portion of the tail lights. How do I know this? I have seen used orange 308/328 tail lights for sale on Ebay with just such damage, and the seller explained that he installed the "halogen back up light" conversion, and ruined his. I also saw a 308 at a car club gathering once, and the owner admitted using the halogen bulbs too.

    Use at your own risk...but I wouldn't.

    I just don't understand why you would want to change them in the first place?

    Driving lights I can see. They give better light. That has a positive effect on safety but reverse lights?

    Martin,

    If you had to back down my 150 ft long driveway in the dark with no street lights, you wouldn't ask-- trees on one side and rocks and a dropoff on the other. I changed mine to halogen then changed them back again after the lamps in my daily driver melted the housing. Anyone want to buy some slightly used 50W lamps?....

    Right - I've seen the melting thing happen quite a lot. If you park the car with it in reverse and the key on, then the lights will be on. Not worth the risk, in my opinion...
