Parking lamp failures, is LED the fix?

[Psycho75]

Ok so I am about done with all of the turn signal bulbs I have had to replace. I know they ride like 50 year old trucks especially when they are lowered like mine is. My 65 has popped at least half a dozen in the same number of months. I have since learned to lower the hood slowly but it seems like any road jarring is also causing enough impact to pop a filament. My question is should I try the LED bulbs for the front turn signals? If they survive they are worth the $25 a bulb to me? Do I need an electronic flasher if I only replace the fronts and not the back ones. Does it have to be normal or reverse polarity? I have tried researching it on the forums and just not getting the specific answers. Could it be as simple as adjusting my hood down so that it sits on the stoppers when latched? Any help or input is appreciated. Thanks all
